Genus of Ceylon Batrachians. 129 
markable cutaneous expansion on the side of the trunk between 
the fore and hind limbs covered with granule-like tubercles, 
with a few smaller ones on the tympanum. The smooth 
portion of the skin of the back is separated from the rough 
head by a somewhat elevated ridge, caused by a depression of 
the head, and running in a line across just behind the orbits, 
and continued into the linear fold behind the tympanum, a 
good deal like that in the adult Rana Kuhlit figured by 
Dr. Giinther, ‘Indian Reptiles,’ t. xxvi. fig. A. Limbs of 
moderate length ; the length of the body two tenths of an inch 
longer than the distance of vent from heel. The third finger 
is about one tenth of an inch longer than the fourth, which is 
slightly longer than the second; these three fingers form a 
palmated group in advance of the first, and are very slightly 
webbed. First finger about half the length of the third. 
Metatarsus with a small tubercle below the first toe. The 
fourth toe (including the metatarsus) is exactly one half the 
length of the body; the third toe is slightly longer than the 
fifth ; a very short web between the first, second, third, and 
fourth toes only ; the fifth appears to be quite free. 
Upper parts (in spirits) dark brown, with lighter-coloured 
spots; outer parts of hind and fore limbs clouded with brown ; 
inner sides and the cutaneous expansion coloured dark grey, 
with small brown spots; belly dark livid colour; throat suf- 
fused with brown. 
The following are the dimensions of the only specimen in 
my possession—length of body 1°8, vent to heel 1°6, hind 
limbs 2°8, fourth toe (including the metatarsus) 0°9 inches. 
I do not know any frog with which to compare this one in 
its general appearance and character. It is one of a few set 
aside from my collection by Major Beddome, when on a visit 
to Colombo lately, and pronounced by that gentleman to be 
new to science, and which, from a feeling of delicacy, he 
declined to accept from me. In searching for its place in the 
synoptical list of the characters of the genera of Batrachians 
given in page 400 of Giinther’s work on Indian Reptiles, I 
felt that it could scarcely be removed from the first division, 0, 
of the group of Ground-Frogs; and it seemed most closely 
allied to the genus Xenophrys, of which one species, X. monti- 
cola, is described and figured by Giinther in the work referred 
to, p. 414, and plate xxvi. fig. H. 
In the generic and specific descriptions which I have given 
for this supposed new Ceylon frog, I have followed the exact 
order of Dr. Giinther’s description of the Indian frog above 
referred to, to facilitate comparisons between the two.
