Family I. Cyprinidæ.

(Carps.)

In this very extensive Family, comprising so many of our well-known and familiar river-fishes, the mouth is small and shallow; the jaws are feeble and destitute of teeth; but the pharynx (or entrance of the gullet) is defended by strong teeth which compensate for the feeble armature of the jaws: the tongue is smooth. The form is somewhat compressed, and symmetrical; the body covered with scales, which are generally large; the fins are destitute of scales; the rays are soft, the membrane somewhat opaque: there is but one dorsal, generally placed near the centre of the back: the gill-rays are few in number. The stomach is continuous, and the intestine is not furnished with any cæcal appendages.
