Body moderately depressed. Head moderately depressed, H to 

 If times as loug as broad, its depth equal to the distance between the 

 centre of the eye and the tympanum, its length o| to 4| times in 

 length to vent in males, 4^ to 5J times in females ; snout obtusely 

 pointed, with sharp canthns and feebly concave loreal region, as loug 

 as the postocular part of the head ; a shai-p keel below the eye. Pileus 

 2 to 2^ times as long as broad. JS'eck as broad as or a little narrower 

 than the head. The hind limb reaches the shoulder or between the 

 shoulder and the ear, rarely the ear, in males, the wrist, the elbow, or 

 the axil in females ; foot 14 to 1\ times as long as the head ; digits 

 feebly compressed. Tail 1^ to '2\ times as long as head and body. 



Upper head-shields strongly and coarsely striated, or with keels 

 and granular asperities, sometimes nearly smooth in the very young ; 

 nostril pierced between 3 or 4 shields ; nasals forming a sutvire 

 behind the rostral ; frontonasal broader than long* ; prefrontals longer 

 than broad, forming a median suture or separated by one or two 

 agygos shields! ; frontal as long as or a little longer than its distance 

 from the end of the snout, li to 2 times as long as broad, narrower 

 behind than in front; parietals longer than broad; interparietal 1^ 

 to 2 times as long as broad, in contact with a shcirter but often broader 

 occipital. 4 supi-aoculars, first and fourth small, rarely divided into 

 two, first in contact with the frontal, with rare e.vceptions, fourth 

 often separated from the frontoparietal ; 8, rarely 4, superciliaries, 

 second very loug ; a com}>lete series of granules between the supra- 

 oculars and the superciliaries. ;J: Nasal usually divided into an upper 

 and a l()wer, sometimes single, followed by twcj superposed post-

 temporals, anterior usually the longest and usually in contact with 

 the fourth supraocular ; temporal scales moderately large, hexagonal, 



* Lon<^-itudip.ally bisected in a yoiing from Kutnaij^herry ; Stoliczka lias 

 observed a similar division in 3 specimens (out of :iO) from Agia. 



t Out of 78 specimens examined 41 have the prefrontals in contact, 33 have 

 them separated by one shield, and 4 by two shields. 



X A second, inc<)iiii>lete series in a youn*^- from the Punjab. 



§ In a half-grown specimen from Cutch the nostril is pierced between an 

 upper and a lower nasal and a single postnasal formed of the fusion of the two 

 normal shields. 



j 3 or 3-1' in 5 specimens, o 4 in t (Thai' and Kutrco), '> ■") in one (Thar).
