The justification for writing this paper has arisen from 
the fact that Varanus bengalensis, being one of the fairly com- 
mon big lizards of northern India, is a very suitable type for 
dissection, and no detailed description of its vascular system 
seems to exist. It may also serve to supplement the knowledge 
that already exists of the vascular system in Varanus 
griseus, Varanus niloticus, and Varanus exanthematicus. Bed- 
vascular system of the above mentioned species of Varanus, 
and since Varanus bengalensis differs from them in some 
important points of detail, a note on the above, as well as on 
some other points not yet noticed by the above workers may 
prove useful. I have dissected about a dozen fresh specimens 
and that precludes any idea of my having worked on a case of 
individual variation. I have to thank Dr. Woodland for very 
kindly going through and correcting the manuscript of this 
conform to the condition found in other species of Varanus 
and Heloderma, but differ from that prevalent among the La- 
certilia. They however differ from the other species of Vara- 
nus in one important fact that they do not give out the 
paired lateral abdominal veins, unless the latter may be said 
to be represented by a pair of very § ort and inconspicuous 
veins ending in the lateral parieties (fig. 1, v.lat.) r 
(pelvic veins) receive blood by a large 1 
the fat bodies (fig. 1, v.fat), the ventral surface of pelvis (fig. 1, 
v.w.), from the ventral and lateral parieties and from the hind 
limbs. A median ventrally situated vein bringing blood from 
the hind limbs (fig. 1, v.A.1.) meets at the coniluence of the 
roots of the abdominal vein. Anteriorly the anterior abdom-

Epigastric veins—In addition to two lateral (paired) 
epigastric veins (fig. 2, r Lepig. and Ll.epig-), a third which 
may be called the median epigastric (fig. 2, mepig.) is also
