25°83 (Proteles). Its least proportion in Felis is 20°8. Its least pro- 
portion in the Viverride is 13°8 (Viverricula), and its greatest is 
22:0 (Suricata and Galidictis). 1 have found it equal to the humerus 
in length in the Wild Cat and Yossa, and almost equal in Hemiga- 
lidia. Ihave only found it absolutely longer than the humerus in 
Lupleres and Crocuta. 
The radius and ulna are long and slender in Fossa, Galidictis, and 
Eupleres. In Hemigalea the radius (which is a good deal bowed) 
is furnished with a singular plate-like expansion towards and at the 
ventral end of its outer or radial border. A more or less rudimen- 
tary development of the process may occur also in Paradoxurus, and 
a trace of it in Cryptoprocta. 
The olecranon may, as in Viverra civetta, be more bent post- 
axiad than in most forms, and than even, relatively, in the Great 
Cats. A remarkable process may be also developed from the ole- 
cranon, extending mesiad. ‘This is seen in Civetta, but attains its 
maximum in Cryptoprocta, where it reminds one of the inflected man- 
dibular angle of a marsupial. This is little developed in Hemigalea,

like process. B. Distal end of tibia and fibula. 
which, however, has a plate-like process, or ridge, developed from 
the middle of the distal fourth of the ventral surface of the ulna, 
extending down to the root of the styloid process; into this plate- 
like ridge the supinator longus, pronator teres, and the (large) pro- 
nator quadratus muscles are inserted. This ridge also exists in 
Viverricula. 
The Manus. 
The greatest length of the manus (measured from the junction of 
the radius and carpus to the end of the third digit), compared with 
that of the spine, is 23-9 (Proteles), the least is 11°5 (Viverricula). 
In Felis I have found it range from 17:0 to 22°0. The greatest rela- 
tive length of the third metacarpal is 12°5 (Proteles), and the shortest 
is 4:2 (Cynogale). The greatest relative length of the third digit 
is 10°0 (Felis), and 9°5 (Suricata) ; the shortest is 5°2 (Viverra). 
The relatively longest third ungual phalanx is 4°5 (Suricata) ; the 
shortest is 1*3 (Viverra). 
The metacarpus is thus proportionally most elongated in Proteles
