In the male the two rows of femoral pores commence as two short 

 parallel longitudinal lines, separated from each other by a narrow short 

 furrow, on the sides of which, (vertically,) the first 5 femoral (preanal), 

 pores are placed. In front of the anus the short vertical portions 

 turn right and left under a nearly right angle, continuing the entire 

 length of the thigh, each supporting 13 more femoral pores. The interval 

 between the anus and the latter is partly occupied by a flat, slightly 

 raised triangular space, covered by rather large, imbricate, rounded 

 scales. In the female the two lines of larger scales carrying the femoral 

 pores of the males, are present, each scale having a small shallow, 

 round depression. The short, longitudinal furrow of the male is either 

 wanting or barely distinguishable, but the triangular space with larger 

 scales, in front of the anus, is present. The species appears to be 

 rather numerous on the hills at Pinang, where the individuals obtained 

 were captured in houses, at an elevation of 2,200 feet. The largest 

 male was of the following dimensions : 



Length of the head, 1| inch. 



Ditto ditto trunk, 3 



Ditto ditto tail, 5f 



Entire length, 10 inches. 



Its habits offer nothing peculiar : it bites fiercely in defence. In 

 captivity it refuses insects. The integuments, when about being renew- 

 ed, are piecemeal torn off by the teeth, and devoured. A single egg 

 deposited was of a spherical form, about half an inch in diameter, of a 

 whitish yellow colour. M. M. Dumeril and Bibron assign Bengal as 

 the Habitat of this species. The specimen originally described by Mr. 

 Gray, some in the Museum of the Asiatic Society, and a number in my 

 own collection, all are from the hills of Prince of Wales Island (Pulo
