These remarkable snakes were caught beneath fallen timber. 

 They were quiet and gentle in their movements, and made no 

 attempt to bite when handled. I kept one alive for a few days 

 in the hopes of learning something of its habits, but difficulties 

 of transport prevented my doing this as long as I should have 

 wished. 



Zamenis moi, sp. n.f 



Maxillaiy teeth 18; eye moderately large; rostral consider- 

 ably broader than deep ; internasals shorter than the prefrontals ; 



* Named after Mr. C. Boden Kloss, to whom I am indebted for two of the 

 three specimens. 



f Named after the Moi people, the aboriginal inhabitants of the country in 

 which it was found.
