RANA OXYRIIYNCHUS. 
inner surfaces of the extremities intermediate between sienna and ochre 
yellow. Webs of hinder feet greenish grey. Irides greenish black, dotted 
with yellow, and a narrow yellow ring round the pupil. 
Form, &c. — Head subconical, nose narrow, almost acute, and prolonged 
considerably beyond the lower jaw, sides of upper jaw slightly convex. 
Tympanum close to the angle of the jaw, circular, slightly depressed, and 
surrounded by a narrow raised ring. Body subovate. Fore leg short and 
rather slender, the outer, the third, and the inner toes of equal length, the 
second about a line and a half longer, all with a distinct tubercle under 
each joint. Hinder extremities long and rather robust, the leg about two lines 
longer than the thigh, the outer and the third toes of equal length, the 
second nearly four lines longer ; they are all connected by a web which 
extends to the distal phalynx of each, not so distinctly, however, in the case 
of the second, a prominent tubercle under all but the distal joint of each toe, 
a narrow, prominent tubercle, about a line and a quarter in length at the base 
of the innermost toe. Back, sides, and thighs more or less rugose from 
raised cuticular folds and oblong warts, the latter most numerous toward 
the head. Length from nose to anus, 2 inches 3 lines ; length of anterior 
extremities to apex of second toe, 1 inch 14 lines ; of hinder extremities to 
the point of the second toe, 4 inches 7 lines. 
Inhabits Kaffir Land and the country about Port Natal. It is closely allied to Rana 
Delalandvi, and may eventually require to be regarded but a variety of that species. I 
make this remark in the conviction that what we at present consider specific differences, or 
at least many of them, will not be found, on more extended investigation, to be more than 
modifications in different specimens of the same species. If the result be different to what I 
contemplate, it will be a distinct species. In Rana Delalandii the palatal teeth form two 
ovate clusters, neither of which extends to the edge of the inner nostril ; the tympanum is 
on a level with the surrounding skin, and not encircled by a raised ring. The tongue is 
broad, short, and subovate, Fig. 16. The second toe of the hinder foot continues of the same 
width to the point, and the web only reaches to the penultimate joint. The outer edge of 
the tarsus inferiorly is margined by a raised cuticular fold ; the liver is distinctly three 
lobed. In Rana oxyrhynclius, the palatal teeth are in a narrow row on each side, and each 
row reach to, or rather extend a little in front of, the internal nostril; the tympanum is 
slightly depressed, and surrounded by a raised ring ; the tongue is narrow, rather lengthened, 
and subovate. Fig. 26. The second toe is sensibly narrow at its point, and the interdigital 
web extends to the distal joint : there is no distinct cuticular fold along the inner side of the 
tarsus, and the liver presents only two lobes. Besides the differences particularized, the 
small intestines and the joints of the hinder extremities are longer, in proportion, in this 
species than in the other.
