![tudinal ridges or folds, about twelve in number, beginning at the fundus (which projects beyond the opening from the psalterium) and gradually subsiding towards the pylorus*. The small intestine was of nearly uniform diameter, -4 inch, when filled with water, and when unravelled 2-3 feet in length. The colon, when disengaged from its spiral coils, was 13 feet in length, making a total intestinal length of 3b feet, or about thirteen times the length of the animal from snout to root of tail. The colon, commencing at 1 inch in diameter, gradually and slightly increased for the space of 3 feet, then contracted rather suddenly to about half that diameter, and so continued until 2 feet from its termination, where it gradually dilated into a capacious rectum. Its walls throughout were thin and smootlif. Fig. 9. I, ileum ; Co, colon; Cm, apes of caecum; a, glandular pouch at com- mencement of colon. The caecum (fig. 9) was 6 long and f in diameter, straight, cylin- drical, obtusely pointed at the extremity, with very thin coats. The ileum enters very obliquely and is bound closely to it by a mesenteric * The stomach of the Pudu, in general form and in the size of its compart- ments, both absolute and relative, closely resembles that of the Musk-Deer; but its walls are considerably thicker and its epithelium lining more developed. In the rumen the villi are not only longer but thicker aud more distinctly clubbed, so that they lie close together, completely concealing the intermediate surface from which they grow, which is not the case in the Musk-Deer. In the reticu- lum the divisions between the spaces are nearer together, more pronounced, and beset with more numerous and coarser papilla;. The 'psalterium is almost of exactly the same size as in the Musk-Deer, but differs greatly in structure, inas- much as the lamella; (as in most Ruminants) are of two kinds, large and small alternating; indeed, in the interspaces are very short ridges, which might be said to constitute a third or smallest order of lamellae. Excluding the latter, the lamella; are altogether of the same number (19) as in the Musk. In accord- ance with the general character of the lining membrane of the stomach, the papillae covering them are larger and coarser than in the latter. The abomasus differs in the greater thickness of its lining membrane, and tho irregularity or even re- ticulating character of the ridges. In a Gazella dorcas dissected at the same time, the 'psalterium was rather smaller than in the Musk, and its lamella; less developed, being smaller and somewhat irregular, but without any distinct alternation of small and large plates. The bottom of the intermediate surface, as well as the sides and edges of the plates, were covered with pointed papilla;. t The colon of the Pudu forms a very simple helicine coil, composed of two complete circles in one direction and of two in the other.
