CHAPTER II.
CLASSIFICATION.
THE following classification includes _only the forms mentioned in the succeeding pages_. The relative value of some of the terms employed in classification is not identical throughout the book. This remark applies specially to the term _group_, which is a convenient one, owing to its not having such a hard and fast zoological meaning as has the term _family_, for instance. The term _group_ is applied in this book to divisions of the animal kingdom of very different classificatory importance.

NOTE. Palaeontological research has disclosed the existence of a great number of forms which seem to connect with one another almost all the orders of fishes as usually recognised. Forms connecting the living Ganoids with the Teleosteans have been especially numerous, so that these terms Ganoid and Teleostean can hardly be any longer used in a precise and scientific sense. This has rendered the subject of the classification of fishes a very difficult one. Though unsuitable for adoption in a work like the present, by far the most natural classification hitherto proposed seems to be that of Smith Woodward[15]. He considers that the course of development of fishes has followed two distinct lines, the autostylic and hyostylic (see p. 119), and groups the various forms as follows:
HYOSTYLIC. AUTOSTYLIC. Subclass 1. ELASMOBRANCHII. Subclass 3. HOLOCEPHALI. 1. Ichthyotomi. 1. (unknown). 2. Selachii. 2. Chimaeroidei. 3. Acanthodii. 3. (unknown).
Subclass 2. TELEOSTOMI. Subclass 4. DIPNOI. 1. Crossopterygii (Palaeozoic 1. Sirenoidei. and Mesozoic). 2. Crossopterygii (Cainozoic). 2. (unknown). 3. Actinopterygii. 3. Arthrodira.
The primitive forms in each of these four subclasses have the fins archipterygia (see p. 127).
