SUMMARY

The preceding analysis of the amphibians and reptiles of the state of Michoacan shows that the herpetofauna is composed of 176 species and subspecies definitely recorded from the state, plus ten others that probably occur there. Ten species are reported for the first time from Michoacan: _Pseudoeurycea robertsi_, _Leptodactylus occidentalis_, _Microbatrachylus pygmaeus_, _Pternohyla fodiens_, _Hypopachus caprimimus_, _Phyllodactylus homolepidurus_, _Anolis dunni_, _Sceloporus bulleri_, _Sceloporus heterolepis,_ and _Geagras redimitus_. Five species that have been reported previously from Michoacan are based on specimens having unreliable locality data or on misidentifications; therefore, the following species are not considered to be a part of the herpetofauna of Michoacan: _Caiman crocodilus fuscus_, _Urosaurus irregularis_, _Geophis nasalis_, _Tropidodipsas fasciata guerreroensis_, and _Micrurus fitzingeri fitzingeri_.

Systematic studies based at least in part on specimens from Michoacan have resulted in a redefinition of nine species and subspecies: _Bufo marmoreus_, _Bufo perplexus_, _Anolis nebulosus_, _Anolis nebuloides_, _Sceloporus bulleri_, _Sceloporus heterolepis_, _Sceloporus melanorhinus calligaster_, _Hypsiglena torquata torquata_, and _Hypsiglena torquata ochrorhyncha_.

Nine species that previously have been recognized as valid have been placed in synonymy. These are: _Bufo horribilis_ Wiegmann, 1833, and _Bufo angustipes_ Smith and Taylor, 1945, as synonyms of _Bufo marinus_ (Linnaeus), 1758. _Microbatrachylus albolabris_ Taylor, 1940, _Microbatrachylus minimus_ Taylor, 1940, and _Microbatrachylus imitator_ Taylor, 1942, as synonyms of _Microbatrachylus pygmaeus_ (Taylor), 1937. _Phrynohyas corasterias_ Shannon and Humphrey, 1957, as a synonym of _Phrynohyas inflata_ (Taylor), 1944. _Hyla microeximia_ Maslin, 1957, as a synonym of _Hyla eximia_ Baird, 1854. _Hylella azteca_ Taylor, 1943, as a synonym of _Hyla smaragdina_ Taylor, 1940. _Loxocemus sumichrasti_ Bocourt, 1876, as a synonym of _Loxocemus bicolor_ Cope, 1861. _Eleutherodactylus vocalis_ Taylor, 1940, is considered to be a subspecies of _Eleutherodactylus rugulosus_. The populations of _Thamnophis dorsalis_ in the Tepalcatepec Valley are shown to be distinct from those inhabiting the highlands of the state; _Thamnophis dorsalis postremus_ Smith, 1942, is revived for the population in the Tepalcatepec Valley.

Descriptions are given of the tadpoles of _Bufo occidentalis_ and _Hyla bistincta_.
