REPTILES COLLECTED IB CHITRAL.

slipping away into cover so rapidly that it is difficult to capture alive. 

 Many were kilUedin the Fort. The teeth were examined in Nos. 1, 5, 6, 7, 

 8, 14, lo and 16. There were 13 or 14 maxillary teeth before the gap in 

 Nos. 1, 5, 6, 7 and 16 ; and 10 or 11 before the gap in the remainder. 



I have 6 skulls in my collection. The habitat of two is unknown, one is 

 from Karachi and the rest from Chitral (Nos. 1, 8 and 16). 



The dentition is as follows : — Maxillary — 10 to 14 small teeth gradually 

 increasing in size from before backwards, then a gap that would accommo- 

 date one tooth, followed by two enlarged, compressed and obliquely 

 placed teeth, one-third longer to twice as long as the preceding. Palatine — 

 9 to 11, slightly decreasing in size from before backwards. Pterygoid — 15 

 to 24, slightly decreasing in size from before backwards (one in which 

 habitat is unknown has 24, and No. 1 Chitral specimen has 22 and 23, aU 

 the rest from 15 to 18). Mandibular 15 to 20, the anterior and posterior 

 slightly decreasing in size. 



Zamenis ravergieri (Menetr). 



I collected 7 examples of this very elegant species at altitudes varying 

 from about 9,000 to 11,000 feet. Of these 4 were S 6 and 3 c? c? • I 

 do not think it has been previously recorded East of the Hindu Kush, so 

 that its habitat is materially extended. One specimen was picked up in a 

 snow drift at about 11,000 feet apparently dead, but revived in the warmth 

 of the hand. The details of the specimens follow : —
