present. These veins lie closely attached to the ventral body- 
wall. The lateral epigastric vein takes its origin from one of 
the roots (pelvic veins) fairly close to its point of junction 
with the corresponding vein of the other’ ‘side? and ‘enters 
independently into the anterior border of the liver of its side. 
uring its course it receives branches from the fat. body and 
lateral and ventral parieties. In this respect the lateral 
epigastrics resemble the condition found in Varanus griseus. 
. The m 
éver, arises from the ventral parieties in the region of the 
pelvis and in its forward course receives a short branch from 
the anterior abdominal vein. It receives several small 
branches from the ventral body-wall and lies in the median 
line ventrally to the anterior abdominal vein. It is not so 
thick and conspicuous as the lateral epigastrics. Anteriorly it 
bends over to the left side and joins the left lateral epigastric 
vein close to its termination in the liver. This vein has not 
been noted by Beddard in any of the species he has described. 
_ Umbilical vein.—This vein has been described by Beddard 
as occurring in Varanus niloticus and Varanus exanthematicus 
bengalensis. 
Post-caval vein.—Two efierent ‘renal branches (venae 
renales revehentes—fig. 3, v.r.v.) ‘from the kidney, meet at 
their origin in the substance of the ey are continued 
behind the posterior edge of the kidneys and meet in the

efferent renal veins of the post caval, A small vein (fig. 3, 
joins the loop posteriorly in the median line, and may be said 
to correspond in a way to the coccygeo-mesenteric of birds, 
though in this case it does not appear to join the branches of 
the portal vein. This splitting of post-caval into two rena
