with those assigned to Rana labialis by Flower. They are, however, in a less 
advanced stage than the individual figured by him, having the hind legs as mere 
buds. The caudal fin is lower and more sinuous and the dark markings on the head 
and body are slightly dilferent. The mouth-parts are, however, identical and the 
curious patches of granular skin on the dorsal, lateral and ventral surfaces, though 
variable in size and outline, very similar. The integument was of a bright yellow 
colour in life. The patches of granular skin are assemblages of ploygonal multicellular 
glands, each of which is provided with a minute circular orifice, while the whole 
structure is enmeshed in a network of minute blood vessels. 
This peculiar tadpole closely resembles that of the Javanese Rana chalconota,^ 
with specimens of which, thanks to the kindness of Dr. van Kampen, I have been 
able to compare it.

A small but nearly complete series of tadpoles and a young frog of this species 
was found by Dr. F. H. Gravely some years ago in Lady Blake's Drive near Kandy, 
Ceylon. They were living in a small rocky pool the water of which was heated to a 
high temperature by the sun . 
The head and body is stout, oval and rounded, slightly flattened behind the eyes, 
which are large and prominent. The nostrils are small, situated laterally, as a rule 
nearer the tip of the snout than the eye. The spiracle is situated about half way 
down the body, a Httle nearer the vent than the eye: it opens directly outwards on 
a small papilla. The anus is distinctly dextral. The tail is relatively short and deep, 
regularly lanceolate in outline, not much more than one and a half times as long as
