scattered over the head and back in a more or less symmetrical wav. 
Below white with or without grey or black spots which vary in size. As 
in Phrynomantis a pair of fairly prominent glands is found in the 
coccygeal region just above the vent. 
Our largest specimen measures 26 mm. from snout to vent.

11 adult specimens, besides juveniles and tadpoles from the Great 
Karas Mountains. Localities : 1300-1309, 1312, Kraikluft at 4800 to 5000 
feet : 1310, 1311, 1313-1316., 1364, Narudas Slid. 
This species was found breeding in pools which for the most part 
were formed in the river beds after a spate, and were likely to dry up after 
two or three months if not replenished. The metamorphosis of the tadpole 
seems to take place fairly rapidly; several tailless juveniles, 15 mm. from 
snout to vent, were taken ; in other places tailed larvae, their fore-limbs 
not developed, up to 23 mm., were procured. It was noticed that in 
larger and deeper pools the tadpoles were large but not otherwise 
advanced : in shallower pools at higher elevations the tadpoles were 
smaller but much further advanced. A few of the adult specimens have 
the back quite smooth, hut in the majority the back bears small warts. 
The largest specimen measures 47 mm. from snout to vent. 
We have not employed the generic term Pyxicephalus , since we are 
of opinion that owing to the close relationship of R. grayi to R. natalensis 
and perhaps of R. ruddi to the R. mascareniensis group (in respect to 
the presence in of external vocal sacs) the separation of the 
Pyxicephalus from the Rana section proper leads to an unnatural 
arrangement.
