KANGAROOS AND WALLABIES. 



Right Late red Lobe. — This is smaller than the left 

 lateral, and is separated from the cystic lobe by the right 

 lateral fissure. It is concave below for the reception of 

 the right kidney, and presents a partial fissure 3 cm. long 

 on the thin ventral edge. It measures 12 cm. laterally, and 

 10 cm. dorso-ventrally. The inf. v. cava is visible dorsally 

 in its hepatic relationship, which is about 9 cm. long. It 

 is placed on the dorsal aspect of the right lateral and 

 right part of the cystic lobes, between these and the lobus 

 spigelii — its exit being at the back of the right cystic lobe, 

 almost on the level of the gall bladder cleft. 



Visceral Surface. — Here the striking features are the 

 relatively large size of the left lat. lobe, presenting neither 

 fissures nor lobes, and the projection below it, and dorsal 

 to the lesser omentum, of the spigelian lobe, which is 

 broad at the base and pointed at the extremity. 



Left Lateral Lobe. — This lobe, which is separated 

 from the mesial or cvstic lobe bv the left lat. fissure, 

 usually hides part of the gall bladder and its cleft, as well 

 as the smaller left portion of the cystic lobe. In a Wal- 

 laby the left lat. lobe was so large as to occlude completely 

 the two portions of the cystic lobe — gall bladder — and the 

 inner portion of the right lateral lobe. The stomach in 

 Macropus assumes a somewhat V-shape in the abdomen, 

 with a large left portion including the fundus and its 

 single or double pocket and also the abdominal oeso- 

 phagus, and smaller right portion. The left lat. lobe is 

 related to the summit of left portion, whilst the summit 

 of the right portion is related to the right part of the left 

 lateral, cystic, and right lat. lobes — the pylorus, and com- 

 mencement of the duodenum being related to the dorsal 

 or lower part of the right lateral lobe.
