Not illustrated. 1872 edition. Excerpt: ...order (at least after the exclusion of the family of the Pegasidse) has been almost universally admitted. The Pegasidee have been eliminated and raised to ordinal rank by A. Dumeril, with the name Htpostomides; associated with the ordinary fishes by Steenstrup and Giinther; and referred to the order Hemibranchii by Cope. Having seen only alcoholic specimens, and no skeleton of this form, the author has not been able to form an opinion. PIECTOGNATHI. The order of Plectognathi has been almost as universally admitted as the former, but has been criticized by M. C. Dareste,1 and stated to be an unnatural association, whose members had diverse relations. The fishes combined under this name by Cuvier have, however, many characters in common, and are distinguished by the fusion of the several elements of the lower jaw (dentary, angular, and articular) into one; the intermaxillaries and supramaxillaries are more or less closely united; the interoperculum is reduced to a rod-like element, dissevered from connection with the other bones, advanced far forward, and connected by ligament with the lower jaw; the pre-operculum and operculum are articulated with the hyomandibular bone, and the latter, as well as the sub-operculum, are very much reduced in size. The post-temporal unites, more or less intimately, with the skull; the hypo-coracoid is extended downwards. The brain, vascular system, and closed air-bladder do not differ very much from those of the acanthopterygian fishes. Dareste (camille).
