80 StoUczka, on Kaclih Beptiles. [Ma.^, 



present), subcaudals two rowed, slightly enlarged and somewhat irregularly 

 alternating. Toes long and slender, the two last joints separated from the 

 preceding by a very marked thickening, provided with two thickened 

 transverse lamellae on the lower side. 



Colour, above, ashy grey, indistinctly marbled with dark on the head ; 

 8-10 transverse dark bands on the body, composed of more or less confluent 

 spots, and alternating in breadth, the first band on the neck is curved back- 

 wards, and is the continuation of a short dark stripe originating at the pos- 

 terior edge of the eye ; tail above with about twelve or fourteen dark bands. 

 It often occm's that these* dark bands are not well defined, except on the tail ; 

 in some specimens only five bands or rows of spots are seen on the body, 

 and in many they are entirely absent, the colour being quite uniform ashy. 

 Lips dark spotted. Below, uniform whitish, tinged with yellow on the pos- 

 terior half of the body. Young specimens are dark brown, minutely speckled 

 with white, or pinkish. 



The fore-limb does not reach the groin, when laid back, but extends to 

 the tip of snout, when laid forward ; and the hind-limb reaches the ear. The 

 usual size of full grown specimens is about 4 inches, head and body being 

 1-7 and tail 2*3 inches. 



Common throughout Kachh, inostly in crevices of rocks, and very rare- 

 ly seen in houses. 



The species is evidently closely allied to the Ceylonese G. triedrus, 

 Giinther (Ind. Eept. p. 113), but differs from it by the presence of preanal 

 pores, the distinct thickenings at the base of the two terminal joints of the 

 toes, and by its colouration. 



Another species with which it can be compared is the African Gi. scaler, 

 or gecJcoides,^ but judging from Dum. and Bibron's description of that species, 



* The Panjab form wlaicli has been found by Theobald, and which he and Blyth 

 (J. A. S. B., xxii, 410) quote under the name of Gr. geclwides, the latter adding ' perhaps 

 a new species,' is no doubt distinct from the African form, but it is to all appearance 

 identical with G. caspins. In general character it is allied to Kachhensis,h\x.t the shields on 

 the top and sides of head are coarser and carinated, the enlarged tubercles on the body 

 largv r and closer together, in about 12 longitudinal series, separated by one or two rows 

 of minute granular scales, and each of the trihedral tubercles is as large as the opening 

 of the ear ; tail verticillate,above with similar sharply keeled tubercles ; a row of enlarged 

 subcaudals; about eleven upper and eight to nine lower labials; two pairs of enlarged chin- 

 shields, 18-20 longitudinal rows of scales across the belly, with several rows of small 

 scales at the sides ; 32-34 femoral pores, continuous in the preanal region. The fore- 

 limb reaches to half the length of the snout, or the end of it, and the hind-limb is some- 

 what more than half the length of head and body. The colour resembles Kaclihensis, 

 there being five or six indistinct transverse rows of dark brown spots on the upper side. 

 All the specimens in the Museum are very much shrunk, but I can see no essential 

 distinction between them and the description and figure given by Eichwald of his 

 0. caspius in Nouv. Mem. Soc. Moscow &c., tome VII, 1841, p. 114, pi. xv, and also
