Hydrus nigrocmctus, var.. Cantor, p. 129, pi. xl. fig, 8. 



Distira jerdonii, Blgr. Cat. Snakes, iii. p. 299. 



This is apparently a very rare species. Cantor obtained " a single 

 individual, captured in a fishing-stake off Pinang," during his four 

 years in the Straits of Malacca, and it does not seem to have been 

 observed again since his time. 



Hah. Bay of Bengal, Straits of Malacca, Borneo.

Cantor obtained four specimens during four years in the Straits 

 of Malacca, It is recorded from "Bangkok" (Hanitsch, Eep. 

 Eaffles Libr. & Mus. 1897, p. 10).

Siamese. " Ngu chai-tong." 



Cantor writes of this species : — " Incredibly numerous in the 

 Bay of Bengal, at Pinang and Singapore, far more so than any 

 known terrestrial serpent. The fishing-nets are hardly ever 

 worked but one or more are among the contents." The British 

 Museum has a specimen from Siam presented by W. H. Newman, 

 Esq., and there is one in the Siamese Museum from the Gulf of 

 Siam, 933 mm. in total length.

 Siam, the Malay Peninsula and Archipelago, to Papuasia.

Aipysurus eydouxi, S. Elower, P, Z, S. 1896, p. 893. 



The occurrence of this species on the coast of the Malay 

 Peninsula was doubtful, but we now know it to be found at Singa- 

 pore, as I obtained a specimen caught on some flooded land near the 

 Serangoon Eoad in 1896, Length about 500 mm. 



Hab. Coasts of Singapore, Java, and the Philippines.
