This species is known from a single male specimen, from Goalpora 

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

 kindly entrusted to me for description by Dr. Auuandale. 



It is very closely allied to T. sexlineatns, 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. Is^ostril pierced between the 

 nasal, one or two postnasals, and the fii-st 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- 

 yersely elliptic smooth lamellse inferiorly, the distal 

 joint compressed, bent at an angle and covered with 

 narrow lamellae inferiorly. Femoral pores reduced to

 which reproduces the condition known in the Geckouid genus Gymno- 

 Jadylus. In this respect it is more specialized than Tachydromus
