50 Dr. J. E. Gray on the Species of Wyrax. 
milk-canines, South Africa, from Sir Andrew Smith. Mos- 
sambique, Tete (Peters, Kirk). . 
There is no adult specimen of this species in the British 
Museum ; there is a young specimen, with the milk-teeth, re- 
ceived from Sir Andrew Smith, the original describer of the 
species. It is so different from the young specimen of the 
West African species received from M. Verreaux, which agrees 
with the adult tropical species described by Mr. Fraser, in the 
British Museum Collection, that there can be no doubt that 
the South and West African species are distinct, though the 
French zoologists and osteologists have confounded them. 
The young specimen is at once known from the young of 
D. dorsalis by the paler colour of the fur, the want of the dark 
dorsal streak, and the whiteness of the under surface. 
Dr. Peters, in his ‘Mammalia of Mossambique,’ says that 
D. arboreus is the only species of Hyrax he found in Mozam- 
bique. It occurs near the capital of Mozambique, on the 
coast, and at Tete in the interior, where it is called Mbira. 
~ It would be interesting to know if this is the same as /. 
dorsalis, as the latter occurs at Ashantee. 
Common on rocky hillsides, living in colonies. Caught by 
spring-traps; flesh good to eat (Kirk, P. Z. 8. 1864). 
Dr. Peters, in a note to me respecting the Hyraces mentioned 
in his ‘ Mammalia of Mossambique,’ observes, “‘ It may be that 
there are two species of Hyrax in Mossambique—one on the 
coast, and the other in the interior. From the coast I onl 
got a female specimen: the skull of this species shows small 
grinders compared with those of H. syriacus, and seven in 
number.” See further observations on this skull under Huhyrax 
abyssinicus. ‘‘'The other specimen from the interior, the Car- 
nera Hills near Tete, agrees perfectly with the H. arboreus 
from the Cape.” This species is easily to be distinguished 
by its soft fur and want of rusty colour; the hairs of the under- 
side are white, and brownish grey at the base. 
b. Orbit incomplete, Heterohyrax. 
3. Dendrohyrax Blainvillit. 
An adult skull in the British Museum (No. 724 e), without 
its lower jaw, was received from the Zoological Society with- 
out any habitat or history attached to it. It has small, more . 
equal-sized molars and premolars, in a nearly straight line, 
and the great length of the diastema which is so characteristic 
of this section of the genus. It may be the skull of the D. 
arboreus of South Africa. It differs from the skull of D. dor- 
salis in being small, in the forehead being convex in the centre 
between the orbits, and in the orbits beg incomplete behind.
