54 INDIAN TERTIARY AND POST-TERTIARY VERTEBRATA. 
eastern Asia, there are several limb-bones. A slightly imperfect right tibio-tarsus 
(No. F. 315) from bed Cd in the 
Cathedral agrees very closely with 
the corresponding bone of a skeleton 
in the British Museum, and measures 
6*5 inches in length. The distal 
portion of a slightly larger specimen 
of the homologous bone from bed 
Ca in the same cave is represented 
in the accompanying woodcut (fig. 
9), and shows the well-marked bridge 
over the channel of the extensor 
tendons. The distal half of the left 
tarso-metatarsus represented in the 
same woodcut was obtained from 
the Purgatory cave, and exhibits 
very clearly the trace of the divisions 
between the three component bones, 
which is very characteristic of the 
species. 
IV. REPTILIA. 
General .< — Reptilian remains from the Karnul caves are, with the exception of 
those of Varanus , comparatively scarce, and in most cases even generically undeter- 
minable. In addition to the genera noticed in the sequel, there is evidence of the 
existence of one or more small species of emydine, and perhaps also of other tortoises. 
Several fragments of jaws indicate small lizards probably belonging to the Geclconidce- 
and Agamidce , but many of the specimens appear to be of very recent origin. There 
are also some small snakes, which have not been generically determined. 
Crocodilus, sp. 
Tooth. — This genus is represented by a small anterior tooth, probably belonging 
to the lower jaw, from bed Y in the Cathedral cave. 1 
Varanus draoena (Shaw). 
Abundance of remains. — Remains of Varanus are of exceedingly common occur- 
rence in the Karnul caves, and consist mainly of upper and lower jaws and vertebras. 
In the absence of any evidence to the contrary all these remains are referred to the 
common species now inhabiting southern India, which at the present day attains a 
length of four feet. 
Maxilla.— A. right maxilla from bed K in the Charnel-House is represented in
