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. arhoreus^ 

 Smith. It has, if I am not mistaken, much shorter ears 

 than H. arhoi'eus ; and therefore I said the H. arboreus has 

 much shorter ears than H. cajyensis, which is not the case. 

 Dr. Welwitsch's specimen resembles more the H. habessinicus 

 of Ehrenberg in this respect, and may prove to be identical 

 with that species." 



I may add that it differs from H. ahyssinicus 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 Brucei. 



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

The name oiH. syriacus cannot be retained for this species, 

 as it does not come from Syria.
