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

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

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

 2 to 21 times as loug as broad. Neck as bi-oad as or a little narrower

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

 nostril pierced between 3 or 4 shieLls ; nasals forming a suture 

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

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

 agygos shieldst ; frontal as loug 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|^

* Lonijitudinally bisected in a young from Kutnaglierry ; Stoliczka has

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

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



+ A second, incomplete series in a young from the Punjab. 



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