SNAKES OF CEYLON. 213 



Again, when I visited him early in 1920, he told his cooJies to 

 bring in snakes, and five youths brought in ninety trachyprocta 

 on February 29 and March 1. Its favoured altitude appears 

 to be about 4,000 to 6,000 feet, but I have known it up to 

 about 7,000 feet. It has been reported from Ramboda, 

 Hakgala, Nuwara Eliya, Warwick estate, New Galway 

 district (5,000 to 6,000 feet), Diyatalawa, and Kandy. Mr. 

 Drummond-Hay got it plentifully at Lennock estate in the 

 centre of the Uva patnas (3,000 to 4,200 feet). 



Aspidura drummondhayi Boulenger.

General Characters. — As detailed for the genus. Snout 

 subacutely rounded terminally. Tail about one-tenth the
