line extending from near the tip of the snout upwards outside each 

 nostril to the eye, round the eye and in two patches behind it. 



Spiracle sinistral, large and tubular, pointing directly back- 

 wards. 



Tail rather more than twice the length of the head and bod}', 

 stout, with both fin-membranes well developed throughout its 

 length.

Colour an almost uniform dark brown; fin-membranes and. 

 ventral surface a little paler. 



There can be no doubt that the lips form in this species a 

 powerful sucker, as they do even in such tadpoles as that of Rana 

 liehigii. It is the largest Indian tadpole with which I am ac- 

 quainted.

It has been pointed out by Mr. Boulenger and other authors 

 that the larvae of the Oriental genus Megalophrys fall into two 

 groups one of which resembles the larvae of European Pelobatidae 

 and is in no way remarkable, while the other is distinguished from 

 all other known tadpoles by the peculiar structure of the mouth. 

 It is with the latter group that I am at present concerned. 



The first representative of this group to be described was M. 

 Montana (Kuhl), a species not uncommon in hilly districts of Java 

 and the Malay Peninsula but not known to occur in the Indian 

 Empire. This larva has frequently been described and I need only 

 refer to its colouration The whole of the body and tail are dark 

 brown with paler markings along the sides. At altitudes of from 

 2,000 to 5,000 ft. in the E. Himalayas a tadpole of precisely 

 similar structure is abundant in small jungle streams, but it differs 

 in colouration in two particulars, firstly in that the ventral surface 

 is much paler than the sides and secondly that there are dark 

 instead of pale markings on the latter. These markings take the
