fourth above the ventrals. Swpracavdals : In. even rows.

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

 together the range is 175 to 198.

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

 India, hills and low-country in Ceylon. 



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

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

 millardi. The same remark appUes to Willey who reported 

 it common at Dumbara and Nanu-oya, Fearless at BaduUa. 

 and Abercromby around Anuradhapura. I have examined 

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

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

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

 malais, Nilgiri, Wynad, and Cochin hills.
