37. Notes on the Freshwater Fauna of India. No. VIII.—Some 
Himalayan Tadpoles,—By N, Annanvate, D.Sc., C.M.Z.S. 
During a recent visit to Kurseong, which is situated at a 
height of 5,000 feet in the Darjiling district, I was so fortunate 
as to obtain the tadpoles of two of the characteristic Anura of the 
Eastern Himalayas, of a species hitherto not recorded from the 
Indian Empire, and of an unidentified form of interesting 
structure. My visit lasted from May 21st to May 29th, and it would 
seem probable that the species found had spawned about the 
h 
beginning of the hot weather. 
tadpoles are protected against the incidence of sudden floods. It 
is noteworthy that within the genus Rana a variety of larval types 
occur ; but, as I hope to show in the present communication, the 
peculiarities which are so striking in certain tadpoles, have 
omologies in other species which cannot be detected except during 
life. The first tadpole I describe is not peculiar in any way, but 
it occurs in circumstances which apparently do not call for any 
structural modification. 
DESCRIPTION OF TADPOLES.

Maximum total length, 27 mm.; greatest depth of tail between 5 
and 1 of maximum total length, less than twice the depth of the 
caudal muscles; length of tai i at of head and body.

pointing backwards and upwards, very inconspicuous. — ail 
obtusely pointed, constricted at the base. in 
line, lour almost uniform inky black, slightly less intense on 
the ventral than on the dorsal surface. Dental formula +*, 
nd a lower ; both serrated at the free 
but not on the posterior or 
Beak in two parts, an upper a 
edge, Lips fringed at the corners, 
anterior edge, 
s regards the structure of the mouth, this baad che. 
resembles that of Bufo melanostictus,! from which it may be readily 
distinguished by its small, sunken eye and flat head.
