198 Mr. M. A. C. Hinton on a 
described. Underparts from the chest backwards, together 
with the tail and hind limbs, dark brown, scarcely lighter in 
tint than the rump—not peppered with silver, but mottled by 
the partially visible whitish underfur. Fore limbs and hands 
rather paler than legs and feet. : 
‘The comparatively short and thin fur is soft. It becomes 
very thin and short upon the forearm, the under surface of 
which appears nearly bare, while the backs of the hands and 
wrists are but scantily clad, the fingers being, as already 
mentioned, quite naked. This local thinning-out and dis- 
appearance of the fur may be due to excessive abrasion 
arising from what I believe to be the comparatively terrestrial 
habits of the genus, and not to a natural deficiency. ‘The 
hind limbs are better clothed, but the covering is much 
shorter and thinner than in Aonya; on the upper surface the 
fur extends to the bases of the digits, ending off on each toe 
a little above the point at which the web is inserted. 
Skull and dentition as described above for the genus. 
Besides the characters already mentioned, the skull differs 
from that of A. c. Aindet in having the mastoid breadth 
distinctly, the cranial width and height slightly, greater in 
proportion to the length. The remarkable weakness of the 
dentition is well brought out in the comparative measurements 
given at p. 197. 
Measurements of type taken on the skin :—Head and body 
350 mm. ; tail 480. For cranial and dental measurements

- Hab. S.W. Lake Bunyonyi, British Ruanda (long. 29° 50! 
E., lat. 1° 20’ S.). 
Type. Adult female. B.M. no. 21.1. 22.1. Collected 
about August 1920, and presented to the British Museum by 
Capt. J. E. Philipps. An aged female* from the same 
locality also examined. 
2. Paraonyx congica, Lonnberg. 
1910. Aonyx capensis congica, Linnberg, Ark. f. Zool. vii. no. 9, p. 1; 
described from the Lower Congo. 
Lonnberg’s full description and excellent figures of the 
dentition leave no room for doubting that this interesting 
* As Dr. F. Corner pointed out to me, this individual received and 
recovered from a remarkable injury during its life. The right canine 
has been torn out from the upper jaw, the maxilla fractured and subse- 
quently repaired.
