November and Capt. Sewell's, which were in a sUghtly more 

 advanced stage of development, on the coast of Tavoy in spring. 

 A young frog which had already assumed the green back of the 

 adult was taken with Mr. Gravely 's tadpoles.

Mr. Boulenger has given an excellent description of this 

 larva in the " Annali " of the Genoa Museum and has also pub- 

 lished a key whereb}^ those tadpoles of the genus Rana which are 

 provided with large ventral suckers may be distinguished from 

 one another. This key is in the P.Z.S. for 1893. 



Mr. Kemp obtained two tadpoles that agree well with Mr. 

 Boulenger's description in a small stream running into the Dihang 

 R. near Yembung in January. Their hind limbs have not yet 

 appeared. An adult R. afghana was taken at the same place 

 in the same month.

Captain Flower, in the first of the two papers cited after his 

 name, describes and figures the tadpoles of the Malay race {leu- 

 comystax) of this species, his specimens being from Singapore. In 

 his second paper he does the same for tadpoles from Bangkok, 

 which seem to differ in more than one particular from those of 

 the Malay race. I propose here to describe those of the 

 Himalayan and the Peninsular races — the latter from specimens 

 taken in September in Orissa, the former from tadpoles caught 

 in the neighbourhood of Darjiling and identified after breeding 

 out several individuals from the same lot in Calcutta. In both 

 cases the tadpoles were taken in pools of rain-water. 



I.' Tadpoles of Himalayan race [himalayensis). 



Head and body moderately fiat above, ovoid, rounded in 

 front, convex on ventral surface. 



Mouth nearly terminal, comparatively small ; lips relatively 

 narrow, both directed forwards ; upper lip smooth except at the 

 corners, which bear numerous rounded papillae; lower lip with a 

 fringe interrupted in the middle, and consisting of similar papillae 

 about three deep; dental formula i:3-(-3Ji-f-i:2 or i: 

 3 + 3 ! 3; beak in two parts; the upper beak not hooked, the 

 lower crescentic ; both parts massive, both serrated.
