This species is known from a single male specimeu, from G-oalpora 

 in Assam, preserved in the Indian Museum, Calcutta, which has been 

 kindly entrusted to me for description by Dr. Annandale. 



It is very closely allied to T. sexlineatus, but differs in the still 

 narrower head, the shorter tail, the number of series of dorsal plates, 

 the smaller temporal scales, and the total absence of a collar.

Head-shields normal. Nostril pierced between the 

 nasal, one or two postnasals, and the first upper labial. 

 Lower eyelid scaly. Collar distinct. Back with large, 

 plate-like imbricate scales with strong keels forming 

 continuous lines ; sides with granular scales ; ventral 

 plates obtusely pointed, imbricate, smooth or feebly 

 keeled. Digits slightly depressed, with large trans- 

 versely elliptic smooth lamellse inferiorly, the distal 

 joint compressed, bent at an angle and covered with 

 narrow lamellae inferiorly. Femoral pores reduced to 

 3 to 5 on each side. Tail very long, cylindrical.

Distinguished from Tachydromus by the structure of the digits, 

 which reproduces the condition known in the Geckonid genus Gymno- 

 daetylus. In this respect it is more specialized than Tachydromus,
