We have seen a single specimen of this tadpole, which one of us 

 obtained in June, 1911, together with a tadpole of R. limnocliaris, in a 

 small weedy pool some miles from the base of the Eastern Himalayas 

 near Siliguri. The hind legs are well developed and agree with those 

 of the type specimen of R. tytleri, the only species found in tlie district 

 to which this larva could belong. 



The tadpole somewhat resembles that of R. limvocharis. from which 

 it is easily distinguished by its colouration, by the shape of its tail and 

 by the formation of its mouth-disk.

The tadpole of this species has recently been described and figTired 

 from living specimens by Annandale. Attention may, however, be 

 directed to an error in his account of the mouth-disk. The dental 

 formula of the lower lip in normal specimens is usually 2-f2 ; 2 or 3-f 3 : 2 

 and the third row of teeth appears to be divided only in degenerate 

 specimens. In individuals kept in captivity some or all of the teeth 

 on both lips are apt to disappear.

Specimen A is from Calcutta and has the hind legs about half deve- 

 loped. Specimen B is from Damukdia Ghat on the Ganges, and has 

 the hind legs in almost the same condition as specimen A. Specimen 

 C is from Khoolna in the Gangetic delta and has the hind legs fully 

 developed. 



"We give here for comparison measurements of tadpoles of the closely 

 related species Rana nujidosa (from Bangkok. Siam) and R. erassa (from 

 Madras). In both cases the hind legs are fully developed.
