almost the full size of the adult is attained. My tadpoles were 

 identical in the specimens identified by Mr. Boulenger. 

 Distribution. — Burma, Malay Peninsula, Java.

There was a single specimen — identified by Mr. Boulenger — 

 among some reptiles recently sent home from Perak by Mr. Wray. 



Previously known from the Karin Hills.

I obtained the type of this new species on the Larut Hills, Perak, 

 at 3,500 feet elevation in April .1900. It is now in the British 

 Museum. Mr. Boulenger's description is as follows : — 



" Tongue large, pyriform, feebly notched behind. Vomerine teeth 

 none. Head moderate, as long as broad ; snout short, truncate at 

 the end; cantbus rostralis strong; loreal region concave; interor- 

 bital 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 black lumbar spot ; a black canthal and 

 temporal streak; black 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. 



" This species is closely allied to L. pelodytoides, Blgr., from which 

 it may be distinguished by the lesser web and the extraordinary 

 dermal ridges under the toes, a point of structure which is only 

 foreshadowed in the types of L. pelodytoides."
