On Rana Ornatissima, Socage, and R. Ruddi, Blgr. 35 
convex ; snout obtusely pointed, projecting beyond the mouth, as long as or 
a little longer than the eye ; canthus rostralis rounded ; loreal region 
oblique, concave ; nostril a little nearer the eye than the end of the snout ; 
distance between the nostrils much greater than the interorbital width, 
which is much less than that of the upper eyelid ; tympanum very distinct, 
f to f the diameter of the eye, 2 to 3 times its distance from the latter. 
Fingers short, obtusely pointed, third longest, first as long as or slightly 
shorter than the second, longer than the fourth ; subarticular tubercles 
moderately large, moderately prominent. 
Tibio-tarsal articulation reaching the eye ; heels meeting or slightly 
overlapping when the limbs are folded at right angles to the body ; tibia 
3 to 3^ times as long as broad, to 2^ times in length from snout to vent, 
a little shorter than the fore limb, as long as or a little longer than the foot. 
Toes rather short, obtusely pointed, ^webbed, 3 or 3^ phalanges of fourth 
and 2 of third and fifth free ; subarticular tubercles small, feebly promi- 
nent ; inner metatarsal tubercle hard and compressed, as long as or a little 
shorter than the inner toe ; no outer tubercle ; no tarsal fold. 
Upper parts smooth ; a feebly prominent dorso-lateral glandular fold. 
Lower parts smooth, or belly granulate on the sides and behind. 
Olive brown or pale green, with dark olive or blackish, often pink-edged 
spots which may be insuliform or form two longitudinal series on the head 
and back, from the upper eyelids, and two on each side of the dorso-lateral 
fold, which is yellowish or pink ; a yellowish or pink streak on the canthus 
rostralis, on the outer border of the upper eyelid, and above the temple ; a 
dark band on the loreal region and on the temple ; a more or less oblique 
white streak in front of the eye ; sometimes a whitish ring round the tym- 
panum ; a light streak above the edge of the upper lip, which is dark brown 
or black. Belly whitish, lower surface of limbs yellow; throat dark brown 
or marbled with dark brown, with a large angular or Y-shaped light marking 
on each side. 
Male with a very large, bilocular external vocal sac, the anterior part black, 
the posterior white, protruding through a slit on the side of the throat, 
terminating close to the middle of the base of the arm, the slit as long as 
the orbit. Fore limbs not thickened ; in the breeding season a brown callous 
pad is present on the inner side of the forearm, at the base of the second 
and third fingers, and similar callosities cover the upper surface of the three 
inner fingers. 
The type of this species came from Bihe, east of Benguela, and the 
British Museum possesses many specimens obtained by Dr. Ansorge in the 
same district as well as in other localities in Mossamedes. , Southern 
Ehodesia may now be added to the habitat.
