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 described by Sir Everard Home,* who evi- dently has taken his account from the drawing by Mr. Clift, from which our^ is taken : the object of this drawing, however, being to pourtray the modifications of the inner surface of the Kangaroo's stomach, it is artificially dis- posed accordingly. In a full-grown female Kangaroo (Macrapus major), I found the abdominal oesophagus four inches long, and terminating at six inches distance from the left extremity of the stomach : this extremity was folded forwards and to the right in front of the oesophagus ; from the basis of the left cul-de- sac the stomach continued to expand, and descended into the left lumbar and iliac regions, whence it stretched upwards and to the right side obliquely across the abdomen, to the right hypochondrium, where it became contracted Fig.
