78 GECKONID^E. 



lower labials ; mental large, triangular, with truncated posterior 

 angle ; numerous small chin-shields passing gradually into the 

 gular granules, which are feebly keeled. Upper surface of body 

 covered with small, more or less distinctly keeled granules, inter- 

 mixed with irregularly scattered small keeled tubercles ; flanks with 

 small, widely separated, spine-like tubercles. Scales on the limbs 

 keeled. Ventral scales cycloid, imbricate, those under the neck 

 keeled, the others smooth (or keeled in the var. tropidoy aster). 

 Males with 3 or 4 praeaual, and on each side 3 to 5 femoral 

 pores. Tail cylindrical, tapering, above with very small keeled 

 scales and annuli of spine-like tubercles, beneath with larger 

 scales, but no transversely dilated median plates. Brown 

 above, variegated with darker and lighter, these variegations 

 generally forming transverse markings on the back and tail; some- 

 times a light vertebral band ; the spine-like tubercles on the 

 flanks white ; lower surfaces light brown or dirty white, the throat 

 sometimes blackish. 



From snout to vent 1-4 inches; tail 1*5. 



Hub. Ceylon, Southern India ; abundant in houses in Kandy. 

 G. wicksii is from Preparis Island.

Closely allied to G. Icandianus, from which it differs in the 

 following points : The gular granules are larger, flat, smooth ; so 

 are also the ventral scales ; the mental is very seldom truncated 

 posteriorly, and the median chin-shields form a suture behind its 

 point. Males with 2 or 4 praeanal, and on each side 3 to 5 

 femoral pores. Grey-brown above, with darker and lighter spots ; 

 usually a median row of light blotches on the centre of the back ; 

 temples and sides of neck and throat with oblique dark brown 

 lines ; tail with blackish semianuuli ; digits conspicuously blackish- 

 barred ; lower surfaces whitish. 



From snout to vent 1'25 inches; tail 1'7. 



Hob. Southern India, Ceylon ; in forests.

In habit similar to G. Icandianus and gracilis. Digits not 

 dilated, but with rather large plates under the basal part, the most 

 distal of these plates being the largest and longitudinally oval in
