TASMANIAN DEVIL. 



ternal portion — the lobus caudatus — prolonged to the left, 

 as the small somewhat flattened lobus spigelii. Between 

 the caudate and spigelian lobes is a well marked depres- 

 sion, ventral to which pass the portal vein — artery — and 

 common duct. Both the intermediate division and the 

 lobus caudatus form the concavity below for the recep- 

 tion of the kidney Passing up at the inner and back part 

 of the lobus caudatus is the inf. v. cava. Its hepatic re- 

 lationship, which is similar to the preceding, measures () 

 cm. The (esophagus, on its way to the stomach, passes 

 between the left surface of the spigelian lobe and the 

 concavity of the left lat. lobe. The portal interval corre- 

 sponds to the interval between the ventro-internal por- 

 tions of the right and left lateral lobes. Whilst the 

 fundus of the stomach is, as stated, related to the left lat. 

 lobe, the pyloric part of the stomach, and commencement 

 of the intestine, slightly below the duct entrance, are re- 

 lated to the right cystic and right lateral lobes. In the 

 Tasmanian Devil the liver is found in the epigastric and 

 right and left hypochondriac regions, even extending to 

 the right lumbar region. 



Gall Bladder and Z^c/.s.— The Gall Bladder may be 

 described as a conical or ovoid sac, placed in the gall 

 bladder cleft in the mesial or cystic lobe Where the cystic 

 lobe is divided into two parts it lies between the two, but 

 when into three it lies between the left and intermediate 

 lobes. It may or may not project at the anterior edge. 

 The cleft involves the whole thickness of the lobe, and the 

 surfaces forming the cleft are concave. This is more 

 marked in some than in others, and it may be necessary 

 sometimes to divaricate the divisions to see the bladder. 

 Although for the most part completely invested by peri- 

 toneum, it is held by peritoneal bands to the lateral boun- 

 daries of the cleft. These adhesions rarely extend further
