Body moderately depressed. Head moderately depressed, H to 

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

 centre of the eye and the tympanum, its length oj to 4^ times in 

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

 pointed, with sharp cauthus and feebly concave loreal region, as long 

 as the postocular part of the head ; a sharp keel below the eye. Pileus 

 2 to 21- times as loug as broad. Neck 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 2j times as loug 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 suture 

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

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

 agygos shieldsf ; frontal as long as or a little longer than its distauce 

 from the end of the snout, 1^ to 2 times as long as broad, narrower 

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

 to 2 times as loug as In-oad, in contact with a shorter but often broader 

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

 two, first in contact with the frontal, with I'are exceptions, fourth 

 often separated from the frontoparietal ; 3, rarely 4, superciliaries, 

 second very long ; a complete series of granules between the supra- 

 oculars and the superciliaries.J Nasal usually divided into aii upper 

 and a lower, sometimes single, followed by two superposed post- 

 nasals§ ; anterior loreal shorter than the second ; 4, rarely 3 or o,||

 beneath than above and borders the mouth. 2 or 3 large upper 

 temporals, anterior usually the longest and usually in contact with 

 the fourth supraocular ; temporal scales moderately large, hexagonal, 



* Long-ituJir.ally bisected in a young from Rutnagherry ; Stoliczka has 

 observed a similar division in 3 specimens (out of 20) from Agra. 



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

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



X A second, incomplete series in a young 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. 



Il 3 or 3-4 in 5 specimens, 5-4 in 4 (Thar and Kotree), .5- 5 in one (Thar).
