A USTK ALIAN PHALANGERS. 



bile duct, artery, and portal vein, the former being ven- 

 tral, and the latter dorsal. The right part of the middle 

 cystic — right cystic — and the right lateral lobes corre- 

 spond to the left or pyloric part of the stomach. The 

 portal interval or hilum, where we see portal vein, com- 

 mon bile duct, and hepatic artery corresponds to an inter- 

 val between the dorsal part of the mesial lobes and the 

 inner extremitv of the right and left lateral lobes. 



Inf. V. Cava. — This is not seen in its hepatic relation- 

 ship dorsally or ventrally, i.e., is hidden in hepatic tissue. 

 Its entrance is placed at the dorsal part of the inner ex- 

 tremity of the lobus caudatus. 



Lesser Omentum (g astro-hepatic). — From the exit 

 of the inf. v. cava on the diaphragmatic aspect, where it is 

 continuous with the suspensory ligament, it passes ven- 

 trally at the concavity for the oesophagus on the dorso- 

 int. part of the left lateral lobe, and lies along the dorso- 

 int. part of this lobe, between it and the spigelian lobe, 

 being traced to the portal interval. A band is noted 

 ventral to the lesser omentum from the ventral surface of 

 the left lobe to the lesser curvature of the stomach corre- 

 sponding to the angle or bend between the pyloric or right 

 and cardiac or left portions. 



(2.) Pseudochirus. — Visceral Surface. — Left Lateral 

 Lobe. — The important feature is the ventral pro- 

 jection of this lobe, and in a specimen, where the 

 lateral measurement of the liver was 7.5 cm., the left 

 lateral lobe was 5 cm. Dorsally the concavity is noted 

 for the oesophagus ; also one or two fissures on its ventral 

 margin, and some Assuring on its ventral surface. At the 

 inner margin, dorsally we see the spigelian lobe — a 

 pointed prolongation to the left of the caudate lobe —
