cles; lower parts smooth, except the very expansible skin of the 
throat in the male, which is folded. Limbs of moderate length ; the 
first finger is scarcely longer than the second and fourth, which are 
equal in length, the third being the longest. The distance between 
vent and metatarsal tubercles is only a little more than the length of 
the body ; metatarsus with two tubercles, tarsus with a third on the 
middle of its inner edge. Toes tapering, half-webbed, the third being 
a little longer than the fifth; the fourth very slender. Dark- 
brownish olive, with indistinct darker spots on the sides ; lower parts 
white; throat of the male brown, of the female dotted with brown

The British Museum has received several examples of this species 
from M. Barboza du Bocage; they were collected in the province 
Duque de Bragance. 
Phrynobatrachus natalensis, Giinth. Proc. Zool. Soc. 1862, p. 190, 
is identical with Stenorhynchus natalensis, Smith—a frog which I 
omitted to compare when describing Phrynobatrachus. Dicroglossus 
angustirostris, Cope, Proc. Acad. Nat. Sc. Philad. 1862, p. 341, is 
likewise identical with that species. Peters proposed the generic 
name of Leptoparius for that of Stenorhynchus, because the latter is 
preoccupied (Monatsber. Akad. Wiss. Berl. 1863, p. 452); Phry- 
nobatrachus, however, has the priority. 
CysTiGNATHus BocaGiI. (Pl. XXXIII. fig. 2.) 
Similar in habit to C. senegalensis. Head broad and short, with 
the snout obtusely rounded ; canthus rostralis short ; loreal region 
flat, oblique ; eye of moderate size, tympanum rather indistinct, much 
smaller than the eye. Vomerine teeth in two short groups, between 
the choanze, which are small; tongue broad behind, truncated, with 
each hinder corner slightly produced ; fore limbs of moderate length ; 
hind limbs and toes short ; a rather large, compressed, ovate tubercle 
at the base of the inner toe. Upper parts smooth; all the lower 
parts, from the chin to the vent, coarsely granulated ; ; skin between 
the angle of the mouth and the eye granular. Upper parts and 
throat brownish black, the remainder whitish.
