554 SNAKES OF CEYLON. 



fourth above the ventrals. Supracaudals : In even rows. 

 Ventrals : Rounded ; 136 to 153 in males, 139 to 157 in females. 

 Anal: Entire. Subcaudals : Divided; 36 to 47 in males, 30 

 to 43 in females. If the ventrals and subcaudals are taken 

 together the range is 175 to 198. 



(b) Anomalies : The supralabials are rarely eight or nine. 

 Some of the subcaudals are sometimes entire. 



Dentition. — From seven skulls in my collection, five of which 

 are from Ceylon. Maxillary: A pair of canaliculate fangs. 

 Palatine: 4. Pterygoid: 13 to 19. Mandibular: 16 tol9(?21). 



Distribution. — (a) General : Hills of Western Peninsular 

 India, hills and low-country in Ceylon. 



(b) Local : It is dubious whether the snake referred to by 

 Haly, as common in the hills and low-country, is this species or 

 millardA. The same remark applies to Willey who reported 

 it common at Dumbara and Nanu-oya, Pearless at Badulla, 

 and Abercromby around Anuradhapura. I have examined 

 48 specimens. Specified localities are Galle, Kandy, Veyan- 

 goda, Mullaittivu, Madulkele, and Uva Patnas. In India I 

 have had specimens from the Western Ghats, Karwar, Ana- 

 malais, Nilgiri. Wynad, and Cochin hills.

 of the Bombay Natural History Society.) 



Millard 's Hump-nosed Viper. 



Synonymy. — Ancistrodon hypnale* (part). 



History. — Described by me in 1908 in the Bombaj' Natural 

 History Journal (Vol. XXVIII., p. 792). 



General Characters. — Much like hypnale in most particulars. 

 It is a small snake, growing to about 18 inches. Head flat and 

 broadest about midway between the eye and the neck. Snout 

 moderate in length and attenuating to the tip. An angular 

 canthus is present, a more or less pronounced elevation on 

 the top of the nose, and a loreal pit in the side of the face 

 before the eye. Eye moderate, with vertical pupil, and an 

 iris speckled with ruddy gold. Nostril small, and round, 



* Until I described it specimens had been identified as hypnale.
