Of this species, which was not previously recorded from the 

 Malay Peninsula, I obtained an adult female, 854 mm. in total 

 length, near Alor Kedah, in June 1898, who while in captivity 

 brought forth seventeen young, alive. They were expelled at 

 intervals of from ten to twenty minutes ; between whiles she lay 

 quite still, as if exhausted. The young came out head foremost, 

 and were very lively as soon as born, perfectly *' at home " in the 

 water, swimming with ease and speed, but very awkward and 

 sluggish on land ; as soon as born they proceeded to change their 

 skin. If picked up gently in the hand they were perfectly tame 

 and quiet, but if surprised or pinched they bit with promptitude 

 and vigour. Some new-born young of Hypsirhina enhydris which 

 Cantor observed "refused fishes and aquatic insects " and eventually 

 " expired from inanition " ; but these young //. hocourtii fed freely 

 on small frogs {Bana and Microhyla) when only a day or two old. 

 The new-born young were about 220 mm. in length. 



Colour (in life). ? . Above very dark olive- brown, with dark
