Tadpole. 



In March 1893 I found tadpoles of this species iu the clear, 

 swift hill-streams of Penang, about 1900 feet above sea-level ; 

 they frequented the edges of the stiller pools. They are typical 

 Raiia tadpoles in habits and appearance ; the mouth, I find on 

 comparing my drawing with the figure by Boulenger (P. Z. S. 

 1891, pi. xlv. fig. 1 a), seems similar to that of R, esculenta. 



Bescrijjtioa of the Tadjiole. 



Length of body about once and a half its width, about half the 

 length of the tail. Nostrils about halfway between the eyes and 

 the end of the snout. Eyes on the upper surface of the body, 

 nearer the end of the snout than the spiraculum, the distance 

 between the eyes once and a half to twice as great as that between 

 the nostrils, and slightly greater than the width of the mouth. 

 Spiraculum on the left side, pointing backwards and upwards, nearer 

 the anus than the end of the snout, visible from above and from 

 below. Anus opening on the right side, close to the lower edge 

 of the subcaudal crest. Tail about four times as long as deep, 

 acutely pointed ; upper crest convex, slightly deeper than lower, 

 not extending to base of tail ; the depth of the muscular portion 

 of the tail, at its base, about -^ of the greatest total depth. 



Mouth. Beak broadly edged with black. Sides and lower edge 

 of the lip bordered with papillae ; upper lip with a long series of 

 teeth, followed on each side by a short series of very fine teeth. 

 Lower lip with three series of teeth : 1st very short, weak and 

 uninterrupted ; 2nd also uninterrupted : 3rd longer, narrowly 

 interrupted and stronger than the two outer rows. 



Colour (in life). Above light reddish brown, of exactly the same 

 colour as the sand on the bed of the streams they inhabit, mottled 

 in places with darker brown ; a dark brown line through the eye, 

 sometimes other dark lines radiating from the eye. Crests and 

 posterior portion of muscular portion of tail colourless, with
