Tlie dorsal 2Jcirieto-hepatiG vein (cl.p.v., text-fig. 3). The right 

 lobe of the liver has a small elongated appendage on the dorsal 

 side towards its hinder end, which encloses in its whole length the 

 posterior vena cava. Into this appendage opens a vessel from the

dorsal body-wall, the dorsal parieto-hepatic vein, supported by a 

 pocket-shaped fold of peritoneum which, as in Iguana and 

 Heloderma, attaches the appendage to the body-wall. This vein 

 is described by Hochstetter, and by Beddard, who finds it in other 

 species of Varanus, in the same position. The dorsal parieto- 

 hepatic is formed by the union of the dorso-lateral vein from the 

 body-wall with a vertebral vein from the vertebral column ; the 

 dorso-lateral forms an anastomosis with the parietal vein, as 

 previously stated . 



Another vessel opens into the left lobe of the liver at its 

 extreme anterior tip — the gasiro-hejxotk igji.), coming directly
