il6 SNAKES OF CEYLON. 



specimen (No. 11,531) from Mergui. It appears to be rare

 Annandale and Robinson from the Malay Peninsula, but 

 Boulenger says the Skeat Expedition obtained it from Singa- 

 pore. The Indian Museum has a specimen (No. 14,547) from

Synonymy. — Lapemis hardwickei, L. loreatus, Hydrophis 

 pdamidoides, H. hardwickei, H. loreata, H. fayreriana, H. 

 abbreviaius, H. brevis. 



History. — First described by Gray in 1834 from a specimen

 will establish the species. The suture from the nofetril almost 

 always passes to the 1st supralabial, a feature only to be seen 

 in EnJiydrina valakadyen, and rare aberrant examples of 

 L. curtus and Ghitulia ornata among Indian hydrophids. 



Colouration.— Dorsally pale dirty greenish, ventrally pale
