Show 770 MR. W. N. PARKER ON THE INDIAN TAPIR. [Dec. 19, also the oesophagus and duodenum, the latter especially, are represented 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 (ces. ep). In this it differs from T. americanus 1, 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. 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 cardiac end of the oesophagus ; but it narrows slightly after about the first fl inches, the rest of the small intestine having an average diameter of about J-| inch. The liver has been figured by Murie ; hut his sketch differs consi- Fig. 2. Diagram of the liver, from the posterior aspect, three-eighths nat. size. r. c, right, and I. c, left central lobe ; r.
