hair of tte tail less black at the base, and the subapical band nar- 

 rower. SkuU perfect, otherwise like the preceding. 



Hah. Abyssinia (Jesse). 



A second specimen, purchased of Mr. Jesse with the former, 

 differs in the chin and underside of the body being yellowish, the 

 fur longer, and the dorsal spot smaller. 



There is a specimen in the British Museum, received by Brandt 

 of Hamburg as Hyrax syriaeus, said to be from Africa, that is very 

 hke the specimens from Abyssinia above described. 



It is probable that they belong to a distinct species ; but unfor- 

 tunately Mr. Jesse's animals were received without any notes as to 

 when and where they were obtained. I therefore wait for more 

 material, and simply describe them as a variety. 



*** Dorsal streak Unear, white. 



9. Hyrax Bocagei. B.M. 



Pur rather long, soft, pale grey ; hair of back pale grey, blackish 

 at the base, with a very narrow whitish subterminal band and minute 

 black tips ; nape paler ; chin, throat, and underside of body white ; 

 dorsal spot linear, white, hair white to the base. Ears grey, black 

 and naked at the tip. 



Hab. Angola (Bocage, from the Lisbon Museum). 



Skull with a long and very narrow compressed nose. Length 

 of skuH 3^ inches, width at back of orbit If inch. 



There is an indistinct very narrow variety with black rings round 

 the upper part of the neck in front of the shoulders, formed by the 

 crowded tips of the hairs of this part ; but this may have been pro- 

 duced by the shrinking of the skin of the neck and the manner in 

 which the animal is stuffed. This specimen, which was called ITy- 

 rax arboreus, is very distinct from all the other species of the genus, 

 * Hyrax in the length and narrowness of the nose of the skull, and 

 the whiteness of the dorsal streak. 



2. ETTHYRAX. 



SkuU with a distinct narrow sagittal crest the whole length of the 

 crown when adult ; occipital not dilated above ; nose elongate, pro- 

 duced. Diastema elongate, longer than the length of the outer sides 

 of the first three premolars ; grinders in a nearly straight series ;. 

 molars square, larger than the compressed premolars. Orbit incom- 

 plete behind. 



Euhyrax, Oray, Arm. ^ Mag. N. H. ser. 4. i. p. 46. 



The skull is very similar !to that oi Hyrax syriaeus?, H. Brucei, H. 

 Burtonii, and H. capeiisis in general form ; but the space between 

 the upper cutting- teeth and the first premolar is nearly twice as long 

 as in those species. In the H. Briccei it is as long as the length of 

 the outer sides of the first three premolars and the half of the fourth 

 one ; in H. capensis it is only as long as the outer sides of the first 

 two premolars and one-third of the third one. The grinders are
