Lower lip fringed ; a large sucker on the belly immediately be-

This form resembles the tadpole of Rana latopalmata ' (which 
also occurs in the Darjiling district) but differs from it in its 
dental formula, fringed lower lip, and uniform coloration. 
HABITS OF THE TADPOLES. 
The tadpoles of Bufo himalayanus were found in large num- 
bers at Kurseong and at Darjiling (7,000 feet) in small artificial 
ponds, and at the former locality in a large and comparatively 
still pool of a stream. At Kurseong youn toads, in which the 
tail had partly or completely disappeared, were common, while 
at Darjiling most of the tadpoles were still devoid of external 
fore limbs. The young toads were considerably bigger than are 
into a true sucker. Moreover, in the unidentified species the 
margin of the fringed lower lip forms the anterior wall of the 
ventral sucker. a:
