Batrachia. 133 
Further references to this and other similar tadpoles of the genus will be found 
on p. 28 of the paper cited under my name. I am now acquainted with at least five 
larvae of this type, from the Himalayan foot-hills, Burma, the Malay Peninsula and 
Hongkong. They are all very similar in structure and habits, but may perhaps be 
distinguished by the characters noted below.

I am doubtful whether my M. kempii from the Abor country is really distinct 
from Boulenger' s M. boettgeri from South China. The only difference liVely to be 
constant is that in the Abor form the tongue is distinctly notched, whereas it is des- 
cribed in the Chinese species as being entire. I have had no opportunity to com- 
pare specimens. 
In small streams on the Peak at Hongkong, I found a number of tadpoles of the 
genus which I am unable to distinguish from an unidentified tadpole from the Abor 
country. They were abundant both in September and December, 1915, but in neither 
month was I able to find individuals with well-developed limbs.
