The large tadpoles (up to 90 millim. long), from Quetta, 5700 

 ft., for which I am indebted to Dr. Annandale, are remarkable for 

 the very strongh- marked lines of sensory canals, which are black 

 (preservation in formalin). Tail 2 to 2] times as long as body, 

 3 to 3| times as long as deep, obtusely pointed, the dorsal crest 

 not extending on to the body. Nostrils much nearer the eyes 

 than the tip of the snout. Lip moderately developed, bordered with 

 rounded or conical papillae on the sides and below ; a marginal 

 series of upper labial horny teeth and 4 series on each side ; 3 

 series of lower labial teeth, the innermost narrowly interrupted in 

 the middle ; back entirely black.

Distinguished from R. feae by the shorter hind limbs and the 

 shorter first finger. 



[Owing to the looseness of its skin and its peculiar coloration 

 this frog has in life a very different appearance from its allies. The 

 skin falls naturally into irregular folds and when the head is 

 held in the natural position forms a prominent transverse wrinkle 

 behind the eyes. The dorsal surface is dull clay-colour or olivaceous 

 with conspicuous orange spots or blotches of variable size and 

 number sparsely scattered on the back. The head is speckled with 

 black in some individuals. The ventral surface is white with a 

 black reticulation more or less well developed. The pupil of the 

 eye is reduced to a narrow slit in normal circumstances and a trans- 

 verse dark streak runs across the iris at both ends. A similar 

 streak runs verticallj' downwards across the iris above and below 

 the pupil, giving the whole eye a most peculiar appearance. This 

 feature also occurs in the tadpole. The iris itself is golden brown. 



R. sternosignata is extremely common, with R cyanophlyctis, in 

 pools and water-channels in the Quetta and Pishin districts of 

 Baluchistan between 5000 and 6000 feet. Mr. Kemp and I did
