Alimentary canal, Phascogale flavipes. internal surface of the left cul-de-sac was quite smooth and villous (?), while the right half of the stomach was entirely covered internally with rugae, running chiefly in a longitudinal direc- tion, and particularly numerous towards the ;* The stomach in the Wombat and Koala does not materially differ in external figure from that of the above-cited Marsupials ; the oesophagus terminates nearly midway between the right and left extremities, but further from the pylorus in the Wombat than in the Koala. The conglomerate gastric gland is of a flattened ovate form, rela- tively larger in the Wombat than in the Koala, situated to the left of the cardiac orifice, at the lesser curvature of the stomach (fig. 123). The gastric gland has a similar position in the Fig. Beaver, but in this animal the excretory orifices of the gland are arranged in three longitudinal rows, while in the Wombat and Koala they are scattered irregularly ; in the Wombat they are about thirty in number, and the bottoms of the larger depressions are subdivided into smaller cells. In the partially contracted state the inner membrane of the stomach of the Wombat, as represented in the figure, is dis- posed in pretty regular longitudinal rugae, which gradually subside towards the pylorus; but when the stomach is distended these folds disappear, and the left extremity presents a full globular form. In the Wombat dissected by me the oesophagus terminated nearer the py- lorus than is represented in the figure here given from the Comparative Anatomy of Sir Everard Home. The sacculated stomach of the Kangaroo, which offers the extreme modification of this organ in the Marsupial order, resembles the human colon both in its longitudinal extent, structure, and disposition in the abdomen. The natural relative position of this singular viscus is, however, very different from that de
