XIX. — Descriptions of new Batrachians and Reptiles from 

 the Larut Hills, Perak. By G. A. BOULENGEK, F.R.S. 



I AM indebted to Mr. A. L. Butler, Curator of the Selangor 

 Museum, for an opportunity of examining a number of 

 batrachians and reptiles collected by him in the Larut Hills, 

 among which I was pleased to find examples of several unde- 

 scribed species. Unless otherwise stated, types of these new 

 species are preserved both in the British Museum and in the 

 Selangor Museum at Kuala Lumpur. 



Leptobrachiian heteropus. 



Tongue large, pyriform, feebly notched behind. Vomerine 

 teeth none. Head moderate, as long as broad ; snout short, 

 truncate at the end ; canthus rostralis strong ; loreal region 

 concave ; interorbital space as broad as the upper eyelid ; 

 tympanum distinct, half the diameter of the eye. Fingers 

 moderate, blunt, first and second equal ; toes moderate, blunt, 

 webbed at the base only, the web continued as a slight fringe 

 along each side of the toes ; a strong dermal ridge or keel, 

 formed by a modification of the subarticular tubercles, runs 

 along the lower surface of the third and fourth toes, which 

 thus appear to be compressed; a small oval inner metatarsal 

 tubercle. The tibio-tarsal articulation reaches the centre of 

 the eye. Skin smooth, with small tubercles on the upper 

 eyelids. Grey above, with darker light-edged symmetrical 

 markings, the largest occupying the middle of the back; a 

 jlack lumbar spot ; a black canthal and temporal streak ; 

 olack spots on the sides ; dark cross-bars on the limbs ; 

 lower parts grey, speckled with black; a round whitish spot 

 on each side of the breast, at the base of the arm, another on 

 the back of each thigh. 



From snout to vent 33 millim.
