also the cesophagus and duodenum, the latter especially, are repre- 
sented of much too small a diameter and too far apart, thus, as Dr. 
Murie points out, making the lesser curvature smaller than depicted. 
From the cardio-pyloric constriction there extends inwards for about 
2 inches a thickened muscular septum (c.p. /), which partially 
divides the stomach into a cardiac and a pyloric chamber, of which 
the cardiac is slightly the larger. 
The epithelial lining of the ceesophagus extends into the stomach 
for about an inch all round from the cardia (@s. ep). In this it 
differs from 7’. americanus’, in which the cesophageal epithelium 
extends much further over the interior of the stomach, more like the 
arrangement in the Rhinoceros and Horse. The greater part of the 
mucous membrane is very smooth ; but for a region extending round 
the cardiac portion of the greater curvature it is considerably ridged. 
There are also a few slight ridges in the pyloricend. The muscular 
coat thickens considerably towards the pylorus; and there is a well- 
marked circular pyloric valve. 
The duodenum is of considerably greater diameter than the car- 
diac end of the cesophagus; but it narrows slightly after about the 
first 5 inches, the rest of the small intestine having an average dia- 
meter of about ]2 inch. 
The liver has been figured by Murie; but his sketch differs consi-

derably from this gland in the specimen under consideration; and I 
therefore give a figure for comparison (fig. 2), to show that this 
organ, as in many other Ungulates, may vary considerably in form.
