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.
F o rm , &c .— Head subcohical, nose Harrow, 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 óf 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 Sana
Delalandii, 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. IS. 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 Outeredge of
the tarsus inferiorly is margined by a raised cuticular fold; the liver, is distinctly three
lobed. In Rana oxyrliynclius, 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. 2S.' The second toe is sensibly narrow at its point, and the interdigital
web extends to the distal jo in t; 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 thé other.
