470 PROF. ST.-GEORGE MIVART ON THE ZLUROIDEA. [June 6, 
Proteles the scapula is not unlike that of Viverra; the metacromion 
is rather larger and more pointed than in Hyena. In Proteles, 
Hyena, and Crocuta the acromion is shorter than in the Felide or 
Viverride, except sometimes in Eupleres. 
The angle formed by the axillary margin with the spine of the 
scapula varies from about 20° (Suricata, Galidictis, Proteles) to 35° 
(Lion and Tiger). The average angle is a little above 25°. 
The Clavicle. 
The clavicle is always very rudimentary or absent ; nevertheless in 
Genetta I found to be about 1''-6. 
The Humerus. 
The absolutely longest humerus is 315 (Tiger), the largest 
Viverrine humerus is 14:0 (Arctictis). The greatest proportion of 
the humerus to the spine at 100 is 28°5 (sometimes in Felis), the 
shortest is 18°1 (Zupleres). The shortest feline proportion is 23:4 ; 
the greatest Viverrine proportion is 25:0 (dretictis). Crocuta is 
22:0, and Proteles 24:8. The Civet’s humerus, compared with that 
of the Cat, is stouter, with the great tuberosity relatively more pro- 
minent, and the fossa outside it much deeper and larger. The 
supinator ridge is also stronger, while the bony bridge enclosing the 
foramen for the median nerve is more slender. ‘There is some- 
times an olecranal foramen. The humerus of the Genet is more like 
that of the Cat. There is always a condyloid foramen, except in 
Cynogale, the Galidictineg, and the Hyenide. In Paradoxurus 
the internal condyle may be much prolonged. In Aretictis the 
humerus is much broadened out distally, with a rather small condy- 
loid canal and a strong supinator prominence; there is no marked 
pit outside the great tuberosity. In Cryptoprocta exactly reversed 
conditions obtain, as the condyloid canal is very large in that genus 
(at its maximum), and there is a very marked pit outside the great 
tuberosity, as also in Herpestes, Crossarchus, and Hyena. In Her- 
pestes the humerus is much curved. In Crossarchus the deltoid 
surface is very prominent, and the development of the supinator 
ridge and the projection of the internal condyle are at their maxi- 
mum. The deltoid surface is even more prominent in Suricata. 
In Hemigalea the humerus is a good deal bowed, the great tubero- 
sity and the supinator ridge are little developed, but the internal 
condyle is very prominent. In Viverricula, on the contrary, the 
internal condyle projects so slightly that it is almost effaced. In 
the Hyenide the internal condyle is also relatively little developed, 
the deltoid surface is prominent, there is an olecranal perforation, 
and the pit outside the great trochanter may be wide and shallow as 
in Hyena, or wide and deep as in Proteles. 
The Radius and Ulna. 
The absolutely longest radius is 26'-0 (Tiger) ; its greatest pro- 
portional lengths to the spine at 100 are 27°4 (sometimes in Felis) and
