TASMANIAN DEVIL. 



Portal Vein. — Dorsally two main branches are given 

 off on each side — one to the left lateral lobe, and the other 

 to the right lateral, sending branch to the caudate and 

 spigelian lobes. Ventrally, it terminates in two branches, 

 one to the left mesial, and one to the right mesial lobes. 



Pancreas. — Pancreatic tissue mav be traced alono- 

 the common clnct on the right extremity of the gastro- 

 hepatic omentum, up to the portal fissure. Only a rela- 

 tively small amount is found in the back part of the 

 dorsal mesentery, corresponding to the meso-duodenum. 

 I have never been able to trace it in relation to the duo- 

 denal wall and about the common duct after being joined 

 by the pancreatic duct, so that the amount in this animal 

 in the region of the intestine corresponding to the duo- 

 denal loop of other Marsupials may be regarded as insig- 

 nificant. The Tasmanian Devil has a well developed great 

 omentum, which runs from the pyloric region along the 

 great curve of the stomach. It is independent of the 

 dorsal mesentery, by which we mean meso-duodenum— 

 mesentery — and mesocolon, so that no portion of intestine 

 is included in the lesser sac. If we throw the great omen- 

 tum and stomach up on to the chest wall we see dorsally 

 about the root of the mesentery a well defined piece of 

 pancreas, from which strands are traced on to the great 

 omentum. Traced to the left of the mesenteric root, the 

 pancreas passes out to the spleen, but beyond sending 

 several processes on to the great omentum it is really out- 

 side the lesser sac, forming its lower boundary. In some 

 specimens no pancreas can be traced in relation to the 

 body or the right ant. process of the spleen; in others, 

 however, a piece may be found in the lesser sac related to 

 the body of the spleen, i.e., extending towards the fundus. 

 The main pancreatic tissue diffuses itself over the mem-
