narrower than the short occipital; parietal usually more or less 

 distinctly emargiuate on the side for the accommodation of a large 

 supratemporal,* which is sometimes in contact with the fourth 

 supraocular and sometimes not ; temporal scales granular ; masseteric 

 disc usually very large, sometimes moderate or small, sometimes 

 divided into two ; tympanic shield large ; four upper labials anterior 

 to the subocular. f 



21 to 29 scales and granules in a straight line between the symphysis 

 of the chin-shields and the median collar-plate ; gular fold usually 

 feebly marked or indistinct ; collar-edge entire or feebly sen-ated ; 

 7 to 11 collar-plates. 



Scales on body granular, flat, smooth, equal in size, 40 to 53 across 

 the middle of the body, 25 to 31 corresponding to the length of the 

 head, 3 or 2 and 3 to one ventral plate. Ventral plates in 6 longi- 

 tudinal series and 27 to 30 transverse series + ; the plates of the two 

 median series narrower than the others or equal to the outer. Preanal 

 large, bordered by one semicircle of smaller plates, often preceded by 

 a transversely enlarged shield. 



Scales on upper surface of tibia smaller than dorsals, smooth or 

 feebly keeled. 15 to 20 femoral pores on each side. 24 to 29 lamellar 

 scales under the fourth toe. 



Caudal scales forming alternately longer and shorter wliorls, the 

 two median dorsal series more or less distinctly enlarged ; scales 

 truncate and diagonal, strongly keeled, especially on the sides, the 

 outline of which is distinctly serrated, though not to the same extent 

 as in the var. rudis ; 18 to 26 scales in the fourth or fifth whorl 

 behind the postanal granules. 



Both sexes are alike in coloration. Back greyish-ljrown or olive- 

 brown, usually separated from the darker brown sides by a series of 

 round white spots, which may be black-edged and ocellar ; head and 

 back witli small, irregular, often vermicular black spots; sides often 

 with large light, black-edged ocellar spots. Uniform yellow or 

 yellowish-white beneath, the outer row of ventrals blue, or with a 

 series of blue spots, in both sexes. An account of the coloration of 

 fresh specimens is given by Werner. 



According to Werner, the male may reach a length of 204 millim., 

 whilst the female does not exceed 175. 



* Hardly at all in one of the lelenovka specimens and in one from Van. 

 + 5 in one specimen from lelenovka and in one from Van. 

 X 26 to 32 according to Werner.
