is very short, not exceeding the length of the outer side of the 
first two premolars. The shortness and width of this skull at 
once separate it from the skulls of all the species of true Hyrax 
that are in the Museum Collection. This species is only known 
from a flat skin and a skull collected by Dr. Welwitsch and 
named by Dr. Peters as above. 
Dr. Peters, in a note to me, observes, “ I probably made 
a mistake, and the Hyrax (Proc. Zool. Soc. 1865, p. 401) with 
rather harsh and short hair does not belong to H. arboreus, 
Smith. It has, if I am not mistaken, much shorter ears 
than H. arboreus;.and therefore I said the H. arboreus has 
much shorter ears than HH. capensis, which is not the case. 
Dr. Welwitsch’s specimen resembles more the HZ. habessinicus 
of Ehrenberg in this respect, and may prove to be identical 
with that species.” 
I may add that it differs from H. abyssinicus in the skull, 
the short diastema, and the colour and nature of its fur. It is 
more allied to H. Burtonii, but differs in the colour of the fur. 
It is very difficult to state the size of the ears of the different 
species from stuffed or dried skins. 
Dr. Welwitsch says, “It always differs by its larger size 
from a second species living in the interior of Angola.” I 
have not seen any specimens from the latter locality. 
b. Fur soft, close. 
4, Hyrax Brucet. 
Fur soft, close, yellow grey brown, closely and minutely 
punctulated with black; underside white; dorsal streak di- 
stinct, dark reddish yellow; hairs of the back soft, dark grey 
brown, with a narrow subterminal band and a Pie ate tip. 
Skull: interparietal bone oblong, longer than broad.

The name of /. syriacus cannot be retained for this species, 
as it does not come from Syria. 
Dr, Peters, in a note which he sent to me respecting Ehren- 
berg’s specimen in the Berlin Museum, observes, “‘ His Hyrax 
ruficeps is hardly different from H. syrtacus.”” By the second
