only a rudimentary metacarpal or metatarsal bone for either pollex 
or hallux. 
The genus Crocuta, instituted by Gray’ for the Spotted Hyzena 
of South Africa, differs from the two species of true Hyzenas as to 
coloration, and in that its ears are not so elongated and are rounded 
instead of pointed. The hind legs are shorter than the fore limbs ; 
there is no dorsal mane; and there is but a single pair of anal glands, 
one on each side of the rectum, and a transverse band of follicles. 
The clitoris is enormous, and perforated by the urogenital canal *, as 
has been excellently described in our ‘ Proceedings’ by Dr. Watson®. 
The cranium of Crocuéa is like that of Hyena, but that theincipient 
division between the two parts of the auditory bulla is more rudi- 
mentary. As to the dentition *, M+ has a quite minute rounded 
crown. *:* has antero-external cusp much smaller than the two 
other external cusps ; P:8 is very long, as is also era3 pra has not 
two subequal tubercles side by side on its talon, there being the 
merest rudiment of the inner tubercle. 3, has no cusp inside the 
more posterior of its two large cusps; and its talon is quite minute. 
The penis is large and pendulous, and boneless. 
The dorsal vertebree are fifteen in number. 
The characters presented by the group of Hyzenas—the subfamily 
Hyenine—are as follows :— 
(1) There is no pollex. 
(2) There is no hallux. 
(3) The ungual phalanges are not strongly arched. 
(4) The claws are but slightly arched, blunt, and not retractile. 
(5) The auditory bulla is inflated, and shows no external evidence 
of division. 
(6) The bulla is most prominent posteriorly, where it is not 
everted. 
(7) Only a rudiment of a bony septum. 
(8) The bony meatus auditorius is short ; but its anterior lip is 
produced. 
(9) There is a carotid foramen not situated quite so far forward 
as in the Viverride. 
(10) There is no alisphenoid canal. 
(11) The palatine foramina are situated on the anterior half of the 
palate. 
(12) =+ and pr are developed. 
(13) There is no M.3 op Me’.

2 It may be interesting to note that, in the ‘ Journal of Anatomy and Physio- 
logy,’ vol. xiv. (1879), p. 95, there is recorded (in a paper on the homology of 
the sexual organs) the case of a woman formed in the same way as is the female 
Crocuta.
