(Read before the Bombay Natural History Society on 24th November 1904.) 

 This specimen was obtained at Sandarang, Burma, by Mr. E, 

 McDougall, after whom I have ventured to call it. 

 The description is as follows. Male ? 

 Length — 13| inches ; tail 1| inches. 



Rostral in contact with 6 shields, of which the sutures with the inter- 

 nasals and nasals are subequal, and larger than the 1st labials. Portion 

 visible above greater than distance to frontal. Intemasals a pair ; the 



suture between them sub- 

 equal to that between the prse- 

 frontal pair, about one-third 

 the internaso-prsefrontal su- 

 ture. Prcefrontals a pair ; 

 the suture between them 

 about one-third the prsefron- 

 to-frontal suture. In contact 

 with internasal, nasal, 2nd 

 labial, praeocular, supraocular, 

 and frontal. Frontal in con- 

 tact with 6 shields ; the sup- 

 raocular suture rather larger 

 than the rest, which are sub- 

 equal ; length much greater 

 than distance to end of snout, 

 equal to parietals, about one- 

 third greater than supra- 

 oculars ; breadth about three 

 times each supraocular at a 

 point opposite the centres of 

 the eyes. Nasals undivided ; 

 in contact with the 1st and 

 2nd labials ; nostril lying in 

 the middle of the upper half of 

 the shield. Praoculars one ;
