the toes for two-thirds of their length connected by a web; the outermost and the third nearly the
same length, the fourth a little shorter, and the fifth much shorter; the second considerably longer

behind the base of inner toe; a tubercle under each of the joints of the toes. Surface of back and
sides rugose, from a number of oblong and circular glandular elevations and minute warts; upper
surface of head and outer surface of extremities slightly warty; under surface of head, body, and
inner surface of extremities, smooth; under surface of thighs slightly granular. The ground colour of
the upper and lateral parts of the head, body, and outer surface of the extremities, intermediate
between blackish green and brownish red; the head and anterior portion of back tinted with gray;

anus, 1 inch 4 lines; length of anterior extremities to point of longest toe, 6£ lines; of hinder
extremities, 1 inch 7 lines.
Inhabits the country around Port Natal.
So far as figure is concerned, this species has considerable resemblance to Pyxicephalus. LAta
Oxyglossus and Leiuperus, it is destitute of palatal teeth, but is easily distinguished from either of
these by the form of its tongue and the non-visibility of its tympanum.
ARTHROLEPTIS, n. g.
Maxillary teeth short, slender, and closely set; no palatal teeth. Tongue slightly bifid behind
the last two-thirds free. Tympanum distinct. Opening of Eustachian tubes very small and oblong.
Toes of anterior and posterior extremities free.
ARTHROLEPTIS WAHLBERGII, n. s.
Figure slender. Head in front of eyes very short, the sides converging towards the nose; the
latter narrow and rounded. Eyebrows prominent; eyes large and laterally protuberant. Tympanum
small, subovate, directly over the angle of the mouth; a series of minute warts above and behind angle
of mouth. Anterior extremities rather long and very slender; toes free to the base, each, beneath with
several small tubercles. Posterior extremities slender, the toes delicate and without webs, a tubercle
under each joint; apex of toes slightly swollen; the outermost and third toe of the same length, the
fourth about half the length of the third, the innermost much shortest, the second about double the
length of the outermost. Skin of back, sides, extremities, and under surface of lower jaw, smooth;
that of abdomen and under surface of thighs, subgranular or slightly corrugated. Colour of the
upper surface of the head, the back, the sides, and the outer surface of the extremities, rusty ash-gray,
or a tintrintermediate between yellowish; brown and ash-gray,, and variegated with liver-brown: the

or less distinct, immediately.over;the base; of :the fore-legs; an irregular transverse, stripe or two
blotches between the eyes; a diamond-shaped mark on the middle of the back between the fore-legs,
in some individuals only in outline; two spots towards hinder part of back,“one a little before each
hinder extremity; extremities with one transverse bar' to each joint, and a few small dark freckles.
Under surface of .head, and neck; pale brownish red, the latter'freckled with bluish white; abdomen
pale bluish white; under surface or thighs pale brownish .red. Anus encircled with a dark. ring.
Length from nose to hinder extremity of back, 1 inch; of anterior extremities to apex of longest toe,
7 lines; of hinder extremities to. point of longest toe, 1 inch 4 lines. ...
Inhabits the interior of Southern Africa.
This species might be classed in the group Stenorhynchus, were it not that its tympanum is
distinctly visible, and its.toes free to their base.
POLYPEDATES NATALENSIS, n. s.
Head not quite so wide as the body. Back slightly convex:-; sides protuberant; posterior
part of body very narrow. Anterior extremities short, and robust ; toes slightly webbed at the
base, their points moderately dilated. Hinder extremities long, and rather robust ; the basal half of the
toes webbed. Nose rounded; rostral canthus distinct; nostrils lateral, nearer to the nose than the eyes,
and immediately under rostral canthus. Eyes large, but not very prominent. Tympanum distinct, large,
nearly circular, and close to external edge of eye. The skin of upper and lateral parts of the head, back,
and extremities, smooth; of the sides, chin, under parts of the head, belly, and under surface of thighs,
granular; on the sides and belly the granulations are largest, and somewhat oblong. Tongue large,
somewhat pointed anteriorly; free behind for nearly half its length, and deeply bifid. Palatal teeth in
two short oblique rows, one inside of each posterior nostril. Opening of Eustachian tube moderately
large. The ground colour of the upper and lateral parts of the head, back, and the outer sides of the
extremities, pale cochineal-red, variegated with dull duck-green; the variegations are a longitudinal

The individual described (a female) is the only one I have seen, and was found on the leaf of
a thick reed, growing on the marshy banks of a small river a little to the westward of Port
Natal.
