2. Hyrax Burtonit. 
Fur rather harsh, pale yellow grey, very slightly punctulated 
with blackish; dorsal streak small, yellow; the hairs of the 
back rather rigid, black or dark brown nearly the whole length, 
with a moderate yellow tp ; underside pale yellow; inter- 
parietal bone half-ovate, as long as broad.

specimen in B.M. 
The imperfect skull sent by Mr. James Burton from North 
Africa, with the skins, which I have named H. Burtonii 
(No. 7256), is not. quite adult, as the hinder or third upper 
true molar is not quite developed. It is very like No. 724c¢ in 
size, form, and in the form of the crown; but the notch left 
by the interparietal (for it is lost with the hinder part of the 
skull) shows that that bone was of a half-oval shape, and rather 
longer than broad, being rather wider but not near so long 
compared with its width as the interparietal figured as that of 
H. syriacus by De Blainville (Ostéograph. t. 2). This skull 
differs from those numbered 724 ¢ and d in being higher behind 
when placed on its upper grinders,-and in the forehead being 
slightly more convex in the middle below the orbit. 
3. Hyrax Welwittschit. 
Fur short, rather harsh, iron-grey-grizzled; hairs of upper 
part of the back black, with a large white subapical ring; of 
the sides dirty brown, with a white ring; dorsal streak yellow, 
moderate. 
_ Hyrax arboreus, Peters, P. Z. 8. 1865, p- 401 (not A. Smith). 
Hab. Rocky places on the shores of the River Maiomba, in 
the district of Mossamedes (Welwitsch, /. c.). 
The adult skull of H. Welwitschit, lent to me by Dr. Wel- 
witsch, differs from all the preceding in being considerably 
broader in proportion to its length. The nose is compressed, 
the crown is flat to the occipital ridge, wide in front, and gra- 
dually narrowing behind. The interparietal bone (which is 
partly destroyed by a hole made to extract the brain) is very 
_ small and nearly triangular; the teeth are large, and the palate 
rather narrow, compared with the other skulls. The diastema
