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 
ruge, running chiefly in a longitudinal direc- 
tion, and particularly numerous towards the 
pylorus.””* 
The stomach in the Wombat and Koala does 
not materially differ in external figure from that 
of the above-cited Marsupials ; the esophagus 
terminates nearly midway between the right and 
leftextremities, 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. 123.

Beaver, but in this animal the excretory orifices — 
of the gland are arranged in three longitudinal 
rows, while in the Wombat and Koala 
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 rugm, 
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 esophagus terminated nearer the 7 
lorus than is represented in the figure 
given from the Comparative Anatomy of 
Everard Home. 
The sacculated stomach of the Kangaroo, 
which offers the extreme modification of 
organ in the Marsupial order, resembles the 
human colon both in its longitudinal extent, —

The natural relative position of this singu 
viscus is, however, very different from 
described by Sir Everard Home,* who eyi- 
dently has taken his account from the drawin 
by Mr. Clift, from which our fig. 124 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-_ 
a accordingly. In a full-grown female 
angaroo (Macropus major), I found the 
abdominal cesophagus 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 
cesophagus ; 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

of the stomach, following its curvatures, was 
three feet six inches, equalling that of the ani- 
mal itself from the muzzle to the vent. ;
