The animal kingdom : arranged after its organization, forming a natural history of animals, and an introduction to comparative anatomy . e situ-ated on the hinder part of the back, and point forwards; and immediately behind them arethe heart and liver, of inconsiderable size, with a portion of the viscera and the interior organsof generation. The body, of a transparent gelatinous substance, sheathed with a muscularlayer, is elongate, and generally terminated with a compressed tail; the mouth has a muscularmass and a tongue garnished with little books; the gullet is very long; the stomach thin;two ]irominent tubes, on the right side of the bundle of the viscera, serve as passages to theexcrements, and to the eggs or semen. They swim, in ordinary, in a reversed position; andthey can inflate the body with water in a manner which is not yet well understood. Forskal comprised them all under his genus Pterotrachea, which it is necessary to subdivide. The Carinaria, Lam.,—Has the nucleus (formed by the heart, the liver, and organs of generation,) covered with a thin, sym-metrical, conoid shell, with the point curved /^>^. ?^^ts-^y*- backwards, and often raised into a crest; underits anterior margin, the plumes of the branchiaefloat; on the head are two tentacula, and theeyes are behind their One species {Car. q/mbiiim, Lam.) inhabits theMediterranean; another the Indian Ocean {, B.

Rang, should beanimals of this order, whose shell, in place ofbeing expanded, has a narrow cavity, and aspire rolled up on tlie same plane: its con-tour is raised into a thin crest. They are very small shells of the Indian Sea; and in one of them, Laraanon beUeved that he had found the original of the Ammonites. • M.
