Journal of the Proceedings of the Linnean Society - Vol. 4 Zoology
Part 9
The definition of this genus ran as follows:--
Testa subovata, spinosa. Apertura coarctata, ovata, desinens in canalem tubuloso-conniventem.
This was evidently designed for the _Murices_ proper. The other species of the 'Museum' were distributed in the groups of _Cassis_, _Turricula_, _Bulla_, and _Strombus_. The last was defined as follows; "Testa obverse conica, nodosa, labium exterius angulum transversalem superne formans; interius nullum. Columella incurva. Cauda integra."
M. HAUSTELLUM. _M._ caudatus, subinermis, nodosus.
"Suturis" was originally "costis". The printed emendations are "gibbis, adglutinatis", "costati et nodosi", "subtus rima longitudinali clausa", "margine", and the final remark.
M. TRIBULUS. _M._ caudatus spinis subulatis trifariis.
"Olear. Mus. t. 39. f. 1" was cited in the transcript, to which Linnæus had added "Bonan. 269" and "List. t. 902. f. 22", all which synonyms are present in the 'Systema.' The printed additions are "suturis 3 longitudinalibus, adglutinatis, incrassatis", "secundum suturas: superficies transversim striis elevatis distinctis", "recta".
M. CORNUTUS. _M._ caudatus, spinis subulatis serie gemina.
The s. in the reference to Rumphius was a misprint for the written 5: "Pet. Gaz. t. 68. f. 12" (as in the 'Systema') was present in the copy. The expressions "striata", "conicæ", "obliquo situ", and the final remark, are the printed additions.
M. TRUNCULUS. _M._ subcaudatus, spinis simplici serie.
The description of the tail and account of the variety were not originally present: "suturis" was, at first, "plicis", and "adglutinatis" was "antrorsum adnatis".
M. RAMOSUS. _M._ dædaleus triangularis, spira longitudine ventris.
Had the original manuscript been printed, the multitude of species confused under this appellation would have been somewhat lessened. For the cited figures of _M. inflatus_ (Rumph. t. 26. f. A. and Gault. t. 38. f. A), with that of another short-spired _Murex_ (Arg. t. 19. f. C), were separated from the rest, and quoted for a _M. unguis-odor_, the brief definition of which was "_M._ dædalens triangularis, spira ventre breviore."
The published details, and the drawings of the longer-spired and more slender-bodied _Murices_ (Rumph. t. 26. f. l; d'Arg. t. 19. f. E, H.), appeared as _M. lichenoides_.
I consider, then, that in that event the _M. adustus_ (Arg. t. 19. f. H.), which would tolerably suit the definition, would have been considered the typical form, and _M. axicornis_ (Rumph. t. 26. f. l, and d'Arg. t. 19. f. E.), the variety γ.
M. SCORPIO. _M._ dædaleus quadrangularis, spira subcapitata.
The ill-judged final remark was not in the copy.
M. SAXATILIS. _M._ dædaleus quinquangularis, spira contigua.
The idea of this being a mere variety was not expressed in the original.
M. RANA. M. angulatus subdepressus, costis lateralibus.
The R. of d'Argenville was properly referred to the variety B. The "alba", "sulcis transversis", and "Dorsum anfractum simplici cingulo aculeato" were not in the copy.
M. LAMPAS. _M._ angulatus tuberculis nodosis, cauda flexuosa, labio interiore lævi.
The earlier reading of "una alterave ruga" was "uno alterove denticulo."
M. FEMORALE. _M._ angulato-triqueter: angulis antrorsum acuminatis.
The intended name was _M. triqueter_. Grew's engravings (f. 7, 8) of the species were correctly cited, and the erroneous reference to Rumphius was not inserted. The printed additions were unimportant--"exarata", "repando", "sub" before "edentula", and "levissime".
M. LOTORIUM. _M._ angulatus, tuberculis conicis, cauda flexuosa, labio interno rugoso.
"Subter" was a misprint for the written "inter": the "ut in proximis" was a printed addition.
M. RUBECULA. _M._ angulatus, sulcis moniliformibus, costis lateralibus, dorsalique.
"Gualt. t. 49. f. I" was rightly cited as illustrative: "ex" preceded "lineis".
M. RETICULARIS. _Cas._ inæqualis gibba reticulata, cauda elongata.
The erroneous reference to Rumphius was not present in the manuscript. As corroborative of my expressed belief in the identity of the species described in the 'Museum' with the _Triton ! mulus_, it may be observed, that our author has wholly separated this and the allied _anus_ from the true _Tritons_ and _Ranellæ_, and that the original heading corresponds accurately with the peculiar characteristics.
M. ANUS. _Cas._ inæqualis, gibba nodosa, labris rugosis.
"Pet. Gaz. t. 74. f. 9" and "Pet. Amb. t. 6. f. 4" were the unprinted synonyms. The "rugis reticulato-intertextis", "irregularis", and "patens" were emendations.
M. RICINUS. _M._ ecaudatus, ore utrinque dentato.
"Æqualibus, ad labium majoribus" was not in the copy.
M. CAPITELLUM. _M._ ecaudatus ovatus, columella rugosa, labio edentulo, superficie inermi rugosa.
"Alba" followed "edentula", and "Umbilicus ad basin" terminated the description in the original: the word "striis" was a subsequent introduction.
M. TURBINELLUS. _M._ ecaudatus, turbinatus, columella dentata, spinis explicatis.
The printed additions are "anteriores", "nodulosa", "alba", "Cauda vix ulla", and "Variat colore albo spira longiore".
M. CERAMICUS. _M._ ecaudatus, utrinque acuminatus, columella dentata, spinis conicis.
"Rumph. t. 49. f. L." was an unpublished synonym.
M. NODUS. _M._ ecaudatus ovatus, labio denticulato.
As "Gualt. t. 28. f. R." was quoted, and "aut nigris, conicis, obtusiusculis" (a character which probably belonged to some distinct species erroneously supposed to be a variety) was not inserted in the manuscript, I feel convinced that the _Purpura hystrix_ of authors was the species designed in the 'Museum Ulricæ.'
M. HYSTRIX. _M._ ecaudatus edentulus, fauce lævi.
M. MANCINELLA. _M._ ecaudatus, edentulus fauce striata.
This original heading, and the absence of the erroneous synonym from the MS., confirm the received opinion of the identity of the Museum species (not that of the 'Systema') with _Purpura mancinella_.
M. HIPPOCASTANUM. _M._ ecaudatus edentulus, fauce edentula integra, spinis serie triplici.
Gualtieri's erroneously cited figure was not indicated in the manuscript. No specific name had been originally attached to the description.
M. MELONGENA. _M._ ecaudatus edentulus fauce patula lævi, spinis serie duplici.
"Bonan. 3. f. 186" had been added to the synonymy by our author. The details were less copious than in the published edition, "apice solo acuminatus" being the meagre substitute for the entire description from "Spira" to the end.
M. FICUS. _Bul._ caudata, striis reticulatis, spira obtusa.
"Pet. Amb. t. 6. f. 9" was an omitted synonym. The shell described in the 'Museum' was assuredly not the _ficus_ of most writers.
M. RAPA. _Bul._ caudata, striis longitudinalibus, spira acuta.
M. FUSUS. _Turric._ caudata lævis, labio dentato.
"Bonan. f. 121" and the name had been added to the MS. by Linnæus.
M. BABYLONIUS. _Turric._ caudata, transversim angulo sulcata, labio marginali versus basim sinu exciso.
M. COLUS. _Turric._ caudata striata, labio exteriore crenato.
The printed emendations were "longa" and "s. angulati." The name was added by Linnæus. The following unnamed _Turricula_ succeeded the species in the manuscript copy:--
_T._ caudata striata, longitudinaliter sulcata.
Testa parva, striis plurimis secundum anfractus. Anfractus scabri, sulcis longitudinalibus 15. Color anfractuum superne griseus inferne pallidus. Apertura ovata. Rostrum baseos rectum, testæ dimidio brevius. Labium tantum exterius integrum. An filia præcedentis?
M. MORIO. _Strom._ spira subnodosa, labio exteriore intus rugoso.
The synonymy, as might be expected (for Seba was unknown to Linnæus when the descriptions were written), was not in the original.
M. COCHLIDIUM. _Strom._ spira pyramidata, anfractibus planis.
The reference to Seba, the name, and the "Cauda subulata, longitudine testæ" were not present.
M. CANALICULATUS. _Strom._ spira subconvexa, anfractibus distantibus.
The "Anfractus distincti canaliculo per omnes spiras," the name, and the reference to Seba, were the printed additions. "Habitat in Canada. Kalm." was appended.
M. ARUANUS. _Strom._ incurvus spinosus ventricosus, angulo obsoleto.
The objectionable name (for assuredly the _Buccinum Aruanum_ of Rumphius suits not "spinosus") was not present in the original, but had subsequently been added by our author, who seems to have erased the original "Habitat in Canada. Kalm." I doubt not that _Pyrula carica_ was intended.
M. PERVERSUS. _Strom._ inversus.
The wretched engraving of Gualtieri was not cited.
M. TRITONIS. _Cas._ pyramidalis lævis, columella dentata.
"Bonan. 3. f. 188" stood in the place of Seba. The printed additions were "plerisque", "et suturis variis alternis crassis", and the specific epithet. "Genus difficile eruitur" was written after the description, and the following note erased:--"Ad genus retuli ob labium interius adnatum in quibusdam latius, ob suturas verrucosas, ob caudam canaliculatam parum elevatam, ob labium postice dentatum, quæ omnia affinitatem arguunt."
The _Triton nodiferus_ was probably designed by the following description, which succeeded that of _M. Tritonis_:--
_Cas._ (corrected by Linnæus to _Murex_) _Neptuni_. _C._ pyramidalis nodosa, columella dentata.
Testa maxime facie statura et colore præcedentis. Anfractuum angulus summus nodis prominentibus, unde et spira nodosa evadit, quod non in præcedente. Apertura præcedentis. Labium interius magis dilatatum, maximeque planum. Columella non dentata. Habitat Constantinopoli. Edw. Carleson.
M. TRAPEZIUM. _Strom._ spira nodosa, labio denticulato, columella rugosa.
M. ALUCO. _Turric._ recurvirostra, spinosa, serie simplici.
Gualtieri was not cited, and the reference was to "N. Strombus tuberosus" (_Cerithium aluco_), not O. (_C. nodulosum_) of Rumphius. The inner lip was described as "non adnatum, sed prominens": "s. fuscis", and "Variat cauda recta, &c.", were not in the original.
Besides the published species, the following had been written, but omitted in printing:--
TURRICULA ALBA. _T._ alba recurvirostra, anfractibus margine crenulatis.
Bon. 3. t. 84. Rumph. t. 30. f. K. Pet. Gaz. t. 56. f. 4. d'Arg. Conch. t. 14. f. P. Gualt. Test. t. 57. f. D.
Testa lævis. Anfractus circiter 15, margine subcrenati. Color albus, sæpius saturatior ad marginem anfractuum. Apertura ovata, rostro canaliculato, recurvo. Labium interius adnatum, dente unico obsoleto.
This was evidently identical, from its synonymy, with the _M. vertagus_ of the 'Systema.'
TURRICULA SENTICOSA. _T._ reflexo-emarginata, costis reticulatis.
d'Arg. Conch. t. 12. f. O.
Testa gibba, costis sæpius 12 perpendiculari-obliquis, intertextis striis lamellosis transversis ad anastomosases muricatis, unde admodum scabra evadit. Anfractus ventricosi, sæpius x. Color griseus. Apertura ovata, interne striata, emarginata, parum reflexa.
Evidently this was identical with the _M. senticosus_ of the 'Systema.'
M. OLEAGINEUS. _M._ angulis sulcis inæqualibus, labio interiore rugoso, costis alternis.
Gualt. Test. t. 49. f. G. d'Arg. Conch. t. 13. f. M.
Habitus et structura _rubeculæ_, at octies major, nec vivide pictus, sed colore testaceo fasciis fuscis longitudinalibus. Apertura intus saturate crocea, rugis albis.
Apparently this was the _Triton pileare_ of authors,--not the Mediterranean shell (_T. corrugatus_) termed _M. pileare_ in the 'Systema.'
M. PILEUS HELVETICUS. _M._ angulis rotundatis, tuberculis conicis, apertura utrinque canaliculata.
d'Arg. Conch, t. 12. f. D. Rumph. t. 28. f. D.
Testa ovata, admodum inæqualis, adspersa nodis conicis tuberculatis inæqualibus. Costæ latere antico membranaceæ, primæ 2 oppositæ, reliquæ alternæ. Color flavus. Apertura hians, antice et postice canaliculatæ, faux intus striata. Labium exterius dentatum, intus dilatato-membranaceum.
This suits very fairly the _Triton lampas_ of authors; far better, indeed, than does the _M. Lampas_ of the 'Museum Ulricæ.'
M. SUBULATUS. _M._ ecaudatus, pyramidalis.
Testa subulata instar turris, anfractuum undecim, reticulata striis elevatis decussantibus punctis contiguationem eminentibus. Costæ oppositæ et alternæ. Color albus, maculis flavescentibus. Apertura ovata, Labium exterius crassum, intus dentatum. Interius dentato-glabrum.
Both _Triton! maculosus_ and _Ranella candisata_ approach the ideal portrait, yet neither of them precisely agrees.
Under the name of _Trochus turritus_ our author appears to have first described his _Murex radula_.
_Trochus_ exumbilicatus, pyramidatus, anfractibus duplici serie muricatis.
Gualt, t. 58. f. F.
Testa elongata, flavescens s. testacea. Anfractus 16, connexi sutura crenulata, dorso duplici serie instructi punctis eminentibus pallidis. Apertura subtetragona, subtus in canalis rudimentum desineus.
The _Murex Neritoideus_ of the 'Systema' was thus described.
LYRA NERITOIDES. _L._ testa nodosa subrotunda.
Gualt.
Testa crassa, ponderosa, alba cum rubedine tincta, figura Neritæ, magnitudine juglandis, cincta anfractibus 5 e nodis obtusis crassiusculis. Labium interius depressum, longitudine pictum macula ferruginea.
TROCHUS.
Testa conica. Apertura quadrangularis, basi columella contorta, sinu descendens.
The last five words had been substituted for "absque sinu evidente."
T. MACULATUS. _T._ contorto-umbilicatus conicus, vertice subnodoso.
The printed description and the synonymy are so very dissimilar to the written one, that I entertain no doubt that an early definition of _T. Niloticus_ (with references to "Olear. Mus. t. 9. f. 5" and "Bonan. 3. f. 102") was transmuted into that of a granular species, by the addition of "quasi granis exasperata," &c.
T. SOLARIS was not mentioned in the manuscript.
T. PERSPECTIVUS. _T._ crenato-umbilicatus convexus obtusus: margine acuto.
"Bonan. 3. f. 27, 28" was quoted, as illustrative: "costa crenata" not "costa concava", was the earlier reading.
T. HYBRIDUS. _T._ crenato-umbilicatus, convexus, undique obtusus.
The proposed name was _T. spurius_. The "absque carina, rotundata" was "absque angulis, glabra": "albo, flavoque" preceded "variegata".
T. PHARAONIUS. _T._ umbilicatus subovatus striatus, punctis globulosis, labio dentato.
"Habitat in mari rubro, frequens. D. Hasselquist." was written: the final remark was absent.
T. MAGUS. _T._ umbilicatus convexo-conicus nodosus.
The "cinereo nebulosa" was a manuscript emendation by Linnæus.
T. MURICATUS. Except that "obverse" precedes "ovata", both the diagnosis and the details are precisely similar to the printed account.
T. SCABER. _T._ umbilicatus subovatus, sulcis alternis majoribus moniliformibus.
The erroneous figure of d'Argenville was not cited in the original, nor, indeed, was any name attached to the description. The whorls were said to number from 6 to 8 (not 4 or 5); and the aperture was termed "ovata," not "subrotunda." "Pallida", the final remark, and the present construction and enlargement of the passage relative to the inner lip (which at first ran thus, "Labium posticum coadunatum, sinu postico excisum"), had been added by Linnæus himself.
T. LABIO. _T._ exumbilicatus ovatus striato-tuberculatus, labio dentato.
The erroneous figure of d'Argenville was not cited; "variegata" was the earlier reading of "marmorata"; "aliquot" of "et punctis"; "externo" of "margine". Linnæus himself had enlarged the account of the inner lip from the earlier "postice sinu excisum" to its present length.
T. ZIZYPHINUS. _T._ umbilicatus conicus, striis papillosis.
This is clearly not the imperforated _zizyphinus_ of the 'Systema.' Gualtieri was not referred to; "ambitu marginati", and "in aliis clausus", were not in the copy: "columella parum obliqua" was an addition in the Linnean handwriting.
T. TELESCOPIUM. _T._ exumbilicatus pyramidatus, striis exaratus; labio postice recurvato, spirali, integro.
"Bon. 92", and "Klein 26. Pseudotrochus striatus", were the additional synonyms of the MS.
T. DOLABRATUS. _T._ umbilicatus, labio postico recurvato sulcato, ovato-pyramidalis, glaber.
The whorls were at first called imbricated. The "basis rotundata", and "in superioribus vero unica", had been added by Linnæus.
TURBO.
Testa conica. Apertura orbicularis, integra.
T. PERSONATUS. _T._ exumbilicatus inermis convexus, labio postice diducto.
The I of the reference to Rumphius was a misprint for the written 1. A drawing of Gualtieri (t. 64. f. O), which accords not with the description of this species, was an additional synonym. The name had been added subsequently. _Turbo cidaris_ agrees in most respects.
T. PETHOLATUS. _T._ exumbilicatus ovatus lævis, anfractibus sursum obsolete angulatis.
The written version furnishes us with the additional synonyms of "Gualt. t. 64. f. F.", and "Klein 40. t. 2. f. 51."; the latter (also cited in the 'Systema') was added by our author when he admitted the at first excluded 5. 6 of the synonym of Rumphius. The admission of the rounded-whorled variety? was evidently an afterthought.
T. CHRYSOSTOMUS. _T._ exumbilicatus subovatus rugosus striatus, spinis fornicatis.
"Klein 41. t. 7. f. 126" (cited in the 'Systema'), and the printed "in superiore serie majoribus", had been added by Linnæus in the original account.
T. TECTUM-PERSICUM. _T._ exumbilicatus subovatus, spinis obtusis reflexis, subtus papillosus.
"Forte sola varietas sequentis a loco" has been remarked by our author, who did not admit in his MS. the deceptive figure of d'Argenville.
T. PAGODUS. _T._ exumbilicatus conicus spinis obtusis concatenatis, subtus papillose striatus.
Neither "acuminata", nor the inappropriate "rotundata", were in the original account of this well-known species.
T. CALCAR. _T._ exumbilicatus depressus, anfractibus supra spinis fornicato-compressis scabris.
To his printed synonyms Linnæus has added "Gualt. t. 65. f. N. P.", "List. Hist. t. 608. f. 46", and "Klein t. 1. f. 27". The "fornicatis" was an emendation.
T. MARMORATUS. _T._ exumbilicatus subovatus nodosus lævis.
T. PICA. _T._ umbilicatus lævis conicus denticulo umbilicali.
"Habitat in Barbados, Jamaica", which corrects the stated locality of the 'Systema,' and "Bonan. 29, 30", "Pet. Gaz. t. 70 f. 9", were the additional particulars of the manuscript copy.
T. ARGYROSTOMUS. _T._ umbilicatus subovatus, striatus lineis dorsalibus.
The erroneous references to Gualtieri and d'Argenville, were not present: "os argenteum variegatum" was written after the reference to Rumphius, which name belongs to figure 3, not to 4, whose colouring, moreover, excludes it from being illustrative. The intended specific name was "os variegatum."
T. MARGARITACEUS. _T._ exumbilicatus subovatus, (? angulo) dorsali elevato, ore postice diducto.
Rumphius was not referred to in the original, where "subtilissimis" was in the place of "variis": the printed "margine albo" was a subsequent emendation.
T. DELPHINUS. _T._ umbilicatus depressus hispidus, spinis ramosis.
"Pet. Amb. t. 3. f. 1", and "Grew Mus. t. 11. f. 5, 6", were also cited.
T. DISTORTUS. _T._ umbilicatus muricatus undique spinulis brevibus.
The final remark was not in the original.
T. SCALARIS. _T._ cancellatus conicus, anfractibus distantibus.
"Pretium immensum, sæpe 100 ducatorum", was the final remark instead of the printed one. "Pet. Amb. t. 2. f. 9", was an additional synonym in the written version.
T. CLATHRUS. _T._ cancellatus pyramidatus, anfractibus contiguis lævibus.
All the synonyms of the tenth edition of the 'Systema,' together with "Johnst. t. 11. f. 9", were present in the MS., but most of them, together with the final remark, had been subsequently added to the copy by our author.
T. CRENATUS. _T._ cancellatus pyramidatus, anfractibus contiguis supra crenatis.
The details of the 'Museum' were referred to before their publication. "Pyramidalis" was the earlier reading for "turrita"; "sæpe" was absent: "transversim" preceded "crenati."
T. UVA. _T._ cancellatus ovatus, anfractibus contiguis imbricatis.
"Pet. Gaz. t. 27. f. 2. Olivaris" was the unpublished additional synonym, and the intended name was borrowed from that work. "Longitudinalibus" was "transversis" in the copy, where "ut latus planum non conspiciatur exterius distincta linea" terminated the account of the volutions: the colouring ("alba") was not indicated.
T. CORNEUS. _T._ umbilicatus, anfractibus teretibus decussatim striatis, oris margine reflexo.
The "s. cornea", the name, and the "vix manifeste" had been added to the original account, which latter was referred to previous to its publication.
T. IMBRICATUS. _T._ pyramidalis, anfractibus deorsum subimbricatis.
The "præcedentibus tribus", here mentioned, were not those which the species now follows, but nos. 358, 359, 360, after which it was placed in the MS. "Grisea" had been added by Linnæus.
T. REPLICATUS. The entire account of this shell was interpolated in the MS. by Linnæus.
T. ACUTANGULUS. _T._ pyramidalis, sulco unico acuto majore.
The last four words of the details were written subsequently to the earlier description, to which no name was then appended.
T. DUPLICATUS. _T._ pyramidalis, sulcis 2 acutis.
"Bonan. 3. f. 114", and "List. 160. t. 3. f. 7", were additional synonyms; both, however, were quoted in the 'Systema.' The "color albus", and the term "obtusiores", were in the Linnean handwriting.
T. TEREBRA. _T._ pyramidatus, sulcis 6 acutis.
"Bonan. 3. f. 115" was in the place of the doubtful figure of Rumphius; the indicated colouring was simply "pallida": the "obsoletum" was an afterthought.
HELIX.
Testa cochleata, lævis. Apertura subrotunda segmento circuli exempto.
Except _scarabæus_ and _amarula_, the members of this genus were located in the same group as in the published edition.
H. SCARABÆUS. _Morion_ ovatus subanceps, labio utroque tridentato.
The "ovata, adeo" has replaced the earlier "ita", and "angulata" the original "articulata". The account of the aperture was not inserted in the manuscript, wherein "List. Hist. 577. f. 31" and "Klein 11. t. 1. f. 23", had been inserted in the Linnean handwriting.
H. LAPICIDA. _H._ marginata perforata convexa carinata.
"Cincta" was a press emendation. The only written synonym was "Faun. Suec. 1298".
H. OCULUS-CAPRI. _H._ marginata perforata subcarinata.
"Pet Gaz. t. 76. f. 6." was indicated as a synonym. The name was Latinized from the "_l'oeil de bouc_" of d'Argenville who has, however, represented an utterly different shell.
H. CAROCOLLA. _H._ submarginata imperforata carinata, labio interiore recto.
D'Argenville's figure was, evidently, not at first considered sufficiently illustrative to be referred to: it was not cited in the written copy. "Conicoplaniuscula" was the reading for "convexa", "segmento circuli" (the 1/4 without any sequence was absurd) for "semiovata": the size, as usual, was not given.
H. CORNU-MILITARE. _H._ marginata imperforata subcarinata, labio interiore explanato.
The deceptive figure of Gualtieri was not at first cited.
H. CORNEA. _H._ marginata convexa umbilicata, spira plana.
"Faun. Suec. 1304" was in place of the reference to 'Lister's English Conchology,' a work apparently unknown to our author when he first drew up the Museum Catalogue. I doubt the identity of this shell (the intended name for which was _tabellaris_) with the cornea of the 'Systema.'
H. CORNU-ARIETIS. _H._ utrinque depressa.
"List. Hist. t. 136. f. 40" was written by our author in the manuscript copy.
H. AMPULLACEA. _H._ subrotunda, sursum ventricosior glabra.
The original reading of "anfractus superne ventricosi" was "abdomen superne ventricosius". The erroneous reference to Gaultieri was not at first attached to the description. The species of the Museum was evidently distinct from that of the 'Systema.'
H. GLAUCA. _H._ subrotunda acuminata, labro postice marginato.
H. CITRINA. _H._ umbilicata convexa obtusa.
The final remark was an afterthought.
