Here Hunter noticed ' a glandular part on one side, a little way from the pylorus, with many orifices.'' In the Turtle (Chelone) the muscular tunic of the stomach becomes, in the adult, remarkably thick, for due compression of the veo-etable contents ; in the young animal the coats are as thin as in ;^ In this genus, and other carnivorous Chelonia, the cardiac orifice is very wide compared with the pyloric. The Crocodilia present the most complex stomach known in existing members of the Rej^tilian class. The principal cavity is of a rather flattened sub-circular or full oval shape; there is a tendon, fig. 298, i, at the middle of each side, better defined than in Chelonia, and the muscular fibres radiate therefrom, \h. f, f. It communicates by a wide aperture with the oesophagus, and by a very narrow one with the pyloric portion, ib. g, which is a small sub- spherical pouch with a still smaller oblique aperture into the intestine, ib. k. The analogy to the gizzard of the bird is further shown by the fre- quent occurrence of stones in the stomach of the Crocodile.' In all carnivorous Reptiles the prey is swal- lowed whole, and its entry into the stomach is easy : but nothing is per- mitted to pass out into the intestine except the chyme and other fluids. In herbivorous Reptiles the pylorus gives passage to vegetable matters whose digestion is completed in the colon. In the disposition and attachment of the intestinal canal, the.
