Not illustrated. 1893 Excerpt: ...in the majority of Teleosteans. Behind, at the point of its greatest curvature, three carpal cartilages are joined to the coracoid, which are distinguished as propterygium, mesopterygium, and metapterygium, the former occupying the front, the latter the hind margin of the fin. Several transverse series of styliform cartilages (ph) follow; they represent the phalanges, to which the horny filaments (r), which are imbedded in the skin of the fin, are attached. The pubic is represented by a single median transverse cartilage (pu), with which a tarsal cartilage articulates. The latter supports the phalanges and fin-rays. To the end of this cartilage is also attached, in the male, a peculiar accessory generative organ or clasper. The Class of Fishes is divided into 3 Subclasses and 9 Orders: --Subclass I. Teleostei. Heart with a non-contractile bulbus arteriosus; intestine without spiral valve; optic nerves decussating. Skeleton ossified, with completely separated vertebras. Orders: --1. Acanthopterygii. 2. Acanthopterygii Pharyngognathi. 3. Anacanthini. 4. Physostomi. 5. Lophobranchii. 6. Pleclognathi. Subclass II. Paleichthyes. Heart with a contractile conus arteriosus; intestine with a spiral valve; optic nerves non-decussating; or only partially decussating. Orders: --7. Ganoidei. 8. Chondroptcrygii. Subclass III. Cyclostomata. Heart without bulbus arteriosus;, intestine simple. Skeleton cartilaginous or notochordal. One nasal aperture only. No jaws; mouth surrounded by a circular lip. Order: --9. The Lampreys. In many works on Fishes a fourth Subclass, Leptocardii, isadmitted; it comprises the Lancelet (Branchiostoma) only, whichr however, differs so much not only from the Class of Fishes, but from the general Vertebrate type, that in a strictly systematic acco
