MR. W. N. PARKER ON THE INDIAN TAPIR. [DeC. 19, 



also the cesophngus 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. f), 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 oesophagus extends into the stomach 

 for about an inch all round from the cardia (as. ep). In this it 

 differs from 2\ americanus ', in which the oesophageal 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 pyloric end. Tlie 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 oesophagus ; but it narrows slightly after about the 

 first 5 inches, the rest of the small intestine having an average dia- 

 meter of about Jf 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.
