This little snake, which not uufrequently is found in inhabited 

 houses, is recorded from Penang, Singapore, and the Malay 

 Peninsula. The British Museum Catalogue mentions specimens 

 from Siam, presented by Mr. Newman, and from Cambodia, 

 collected by M. Mouhot. Personally I have obtained this species 

 from Penang (sea-level and at 2200 ft. elevation), from Alor Star, 

 Kedah, and from Bangkok and Chantaboon ; all these were of 

 Var. D. 



Description. In eleven Siamese and Malay individuals the 

 number of ventral shields varied from 192 to 207, and the sub- 

 caudal s from 61 to 75. In one specimen from Penang the 4th 

 and 5th subcaudals were single. 



Colour (in life). — Var. D. Above brown, with fine, narrow, 

 yellow reticulations ; a triangular yellow blotch on each side of 

 the occiput, confluent in the centre, forming a collar; labials 

 yellow, all of them or only the anterior ones spotted with brown. 

 Below uniform white or pale yellow. 



Size. A Bangkok specimen measured 540 mm. in total length.
