OTOCBYPTIS. 115 



is more developed in the breeding-season, and in the majority of 

 individuals, at all events, is not coloured at other times. 



From snout to vent 3-2 inches ; tail 4'6. 



Hob. India from the base of the Himalayas to Cape Comorin, 

 and from the Punjab and Cutch (not Sind) to Western Bengal ; 

 Ceylon. 



Mr. Blanford, who has observed thousands of specimens, confirms 

 Jerdon's statement that Sitana is purely a ground-lizard ; it is 

 found in open country as well as in woods. 



Genus OTOCRYPTIS, 



Wiegmann, Isis, 1831, p. 293. 



Body compressed, limbs very long. Fifth toe very short, not 

 longer than first. All the scales keeled, the dorsals heterogeneous. 

 No dorsal crest. No gular fold. Male with a low nuchal crest 

 and a large folding gular appendage ex- 

 tending backwards to the belly, and 

 covered with large scales. Ear concealed. 

 No praeanal or femoral pores. 



Distribution. Ceylon, Southern India. 

 Two species. 



This genus, as regards the structure of 

 the foot, is intermediate between Sitana, 

 in which the fifth toe is absent, and 



~ 38- Pti/ctolcemus, in which it is much elongate,

spite of its hidden tymPanum, Otocryptis is, on the whole, more 

 nearly allied to Sitana than to Ptyctolcemus.

Upper head-scales sharply keeled ; canthus rostralis and supra- 

 ciliary edge sharp, with much enlarged scales ; supraorbital scales 

 large, the inner series forming, with some enlarged scales on the 

 snout, a regular A -shaped figure ; interorbital region with four or 

 five longitudinal series of very small scales ; 9 to 11 upper and as 

 many lower labials. Dorsal scales unequal, the enlarged ones 

 sometimes forming regular longitudinal series ; lateral scales small,
