larger ones intermixed. On the limbs the scales are much larger, two or 

 three on the upper side of the femora particularly so. Gular pouch and 

 fold covered with small scales, which become larger on the lower belly than 

 on its sides. The two rows of sub-caudals are slightly larger and more 

 pointed than the shields on the upper side of the tail. 

 "> General coloration greenish olive, on the top of the head brownish ; sides 



of the entire body more or less distinctly and rather densely reticulated and 

 spotted with black and yellow ; sides of head and neck and the gular sac 

 tinged with purplish blue, labials spotted with blue. Chin mostly yellow ; 

 belly whitish, without spots. Tail brownish above, paler below, in-egularly 

 and indistinctly spotted with dusky. 



Total length of one specimen 16 inches, of which head and body are 

 4*4 and the tail 11 6 inch. The fore limb when laid backwards extends 

 beyond the groin, or almost to the prseanal edge, and the hind limb when 

 laid forwards fully reaches the anterior edge of the eye. 



The above noticed characters readily separate the Nicobar species from 

 T. dilopTius, or T. tuberculatus, lately (P. Z. S. 1872, p. 533, pi. xxxviii) 

 described by Dr. Giinther from the East Indian Archipelago. 



I obtained only two specimens (male and female) on the Nicobar 

 island Tillingchang, but the species did not seem to be rare.

I have two specimens for examination, one a male"* and the other a 

 female (known from dissection). 



The male is six inches of which the tail is 0*9 inch ; there are 24 

 longitudinal rows of scales round the body, and 48 transverse rows along the 

 tail. The two extremities are on either side somewhat in front of the anus, 

 towards which they converge ; they are depressed, each lying in an oblique 

 cavity, the intermediate space of the sacral region being flat, triangular and 

 pointed above the anus. Each extremity is fully as long as the whole head,| 

 it is covered on the upper side by three longitudinal rows of scales, narro^ving 

 towards the end which is occupied by a large, flat, nail-like scale. 



The body of the female is somewhat stout^er ; it measm'es 5*5 inches, of 

 which the tail is only 0"5 inch. The body is again surrounded by 24 

 longitudinal and the tail by 34 transverse rows of scales. On each side in 

 front of the anus is an enlarged scale, separated by three small scales from the 

 anal edge, and just in the place where the extremity in the male originates ; 



* This is in tlie Indian Museum and I am indebted to Dr. Anderson for the oppor- 

 tunity of examining it. 



t In D. NovcB- Quinece the extremity is only as long as the head is broad.
