 72711 (82339) Bangkok Dec. 12, 1925. 



This very common fresh-water snake is well represented in the col- 

 lection. The adult female from Bangkok, No. 70302, measures 

 1,375 mm. in total length, the tail being 275 mm. long. This snake 

 exceeds by 65 mm. the largest one reported by Dr. Malcolm Smith. 



Dr. Hugh M. Smith has been kind enough to furnish me with the 

 following note on this species: "The local name is 'ngu pla' or 'fish 

 snake,' a name borne by several species of similar habits. It (No. 

 70302) was caught on a line baited with a small whole fish. This 

 species has been frequently taken in my yard here. It is said by one 

 of my Siamese assistants to be poisonous when about to have young, 

 but I do not put much credence in the statements of Siamese regarding 

 the poisonous properties of snakes."
