Having no specimen of this species for description, I submit the 

 following diagnosis taken from Boulenger: '' 



Description. — Rostral broader than deep, visible from above; inter- 

 nasals shorter than the prefrontals; frontal once and one-fourth to 

 once and a half as long as broad, as long as or a little shorter than 

 its distance from the end of the snout, a little shorter than the parie- 

 tals; loreal longer than deep; one preocular, wdth a subocular below 

 it; two postoculars; temporals 2 + 2 or 2-f-l; eight upper labials, 



a From ?a, a prefix meaning very; and qjkv^, swift. 



?> Cantor gives no explanation of the name. Perhaps he meant to indicate a snake 

 being like his Coin ber dhumna ( = Ptyas mucosus) , the name of which in Hindu is said to 

 be dhamin.
