One example taken in a pool at Kraikluft in the Great Karas 
Mountains at an altitude of 5000 feet. Length from tip of snout to vent 
31 mm. : greatest breath of head 11*5 mm., and of body 14 mm. Type, 
T. M. Cat. Batr. No. 1317, in the Transvaal Museum. 
The comparatively long projecting snout, the rather small eye, the 
large broad head, the webbing of the feet, and the fact that the discs of 
the fingers are very little expanded are characters which would seem to 
distinguish this species from any known representative of the genus 
Phrynomantis. On the other hand it would seem to be related to 
P. anneciens , Werner (1. c.) by the fact that the head and body are much 
depressed, that the interorbital space is broad, in the absence of a 
cutaneous fold across the palate, in the character of the inner metatarsal 
tubercle, in the length of the hind limb, and by the presence of a prominent 
fold on the side of the head. 
Unfortunately the characters of P. annectens are not fully known, as 
the type specimen is almost certainly very juvenile. The identity of that 
species cannot be established until adult specimens are obtained from the 
same locality as that of the type.

55 specimens from more or less permanent pools in the Great Karas 
Mountains. Localities : 1318-1358, Kraikluft, altitude 5000 to 5300 feet : 
1359, 1360, Sandmund : 1361-1372 ( neque 1361), Narudas Slid. 
In the same pools Ranct delalandi and Xenopus laevis occurred, and 
in one case Phrynomantis nasuta. 
At Kraikluft this little frog was observed to be a burro wer, making 
its holes a few inches deep in the soft mud surrounding the pools ; these 
holes were apparently used for retreat when occasion demanded. We 
may mention that at Prieska in March 1912 when the country was in a 
very parched condition this species was found hidden in cracks of the 
ground near ponds, sometimes at the depths of 12 to 18 inches. 
During daytime the whereabouts of this little frog could be detected 
by the low, somewhat jarring or clicking croak which it would utter when 
approached. 
In these specimens it is notable that the feet are distinctly webbed 
at the base, the webbing being easy to distinguish between the third and 
fourth digits. 
Most of the examples are dark brown or olive above (in one case light 
brown), with fairly large dark spots arranged more or less regularly ; no 
bright green specimens were seen. A white vertebral line is present in a 
few, in three or four of which there is also present a light line on each 
side starting on the back above the shoulder and losing itself about half 
way between the shoulder and the leg. Dorsally the skin is generally 
smooth, but in a few specimens there are small warts ; in one specimen 
(1331) large elongate and smaller blister-like or warty excrescences are
