434 SNAKES OJ CEYLON. 



(6) Anomalies — Prxfronlals : The median one is rarely 

 absent. Temporals : The anterior is sometimes divided into 

 two superimposed parts. Swpralabials : Rarely six. 



Dentition. — From one skull in my collection. Maxillary : 

 Postnodal,* 1. Palatine: Q. Pterygoid:!^. Mandibular : 9. 



Distribution. — (a) Generaal : Bay of Bengal to Chinese sea. 

 Loo Choc Islands. Western South Pacific Ocean. 



(b) Local : Its favoured haunt is the Western South Pacific 

 Ocean, where it is not an uncommon snake. Around the Loo 

 Choo Islands it is a fairly common species. I have examined 

 many of Mr. Owston's collecting from this region. I saw 

 one in the Hong Kong Museum labelled " Pen ang," and there is 

 one in the British Museum from the same place. The eastern 

 side of the Bay of Bengal appears to be the extreme western 

 limit of its distribution. There are t\^o in the Indian Museum 

 from the Nicobars, two from Sandaway Islands, and one from 

 Ramri Island on the Burmese Coast.

 or moderate, with a slight indication of a canthus. Eye

 small or moderate and lateral. Neck more or less evident. 

 Body moderate or long ; depressed, cylindrical, or compressed ;

 glyphous maxillary dentition coupled with the cylindrical tail.
