494 PROF. ST.-GEORGE MIVART ON THE ZLUROIDEA. [June 6, 
galea it is inserted into the large plate-like process of the radius, 
before described (fig. 2). 
The extensores carpi radiales longior et brevior and the supinator 
brevis are as in the Cat and Civet. 
The extensor communis digitorum supplies the four outer digits 
in the Hyeenas and Civet, as in the Genet and Cat. 
The extensor minimi digiti is substantially as in the Cat, and sup- 
plies the 3rd, 4th, and 5th digits in the Civet, but in the Hyzenas it 
only goes to the 4th and 5th’. 
The extensor longus ulnaris is as in the Cat. 
The extensor ossis metacarpi pollicis is as in the Cat, save that its 
origin extends up inside the olecranon. It is recorded as arising 
from the olecranon in the Civet (but not in the Hyzenas), and as 
inserted into a sesamoid at the base of the first metacarpal according 
to Macalister *, and exclusively into the metacarpal of the pollex ac- 
cording to Mr. Young. 
The extensores indicis et secundii internodii pollicis are as in the 
Cat, save that their origin does not extend up to the olecranon. 
The extensor s. i. pollicis is wanting in the Hyznas, but present 
in the Civet, where it goes to the pollex and index. 
The pronator teres is asin the Cat. In the Civet its insertion 
extends down to the lower end of the radius. It is shorter and 
more slender, relatively, in the Hyznas. In Hemigalea it is inserted 
into the singular plate-like process of the radius. 
The palmaris longus is inserted into the palmar fascia, as in the 
Cat and Hyenas. In the Civet it is said to be large (more or less 
double) and inserted into the pisiforme. It is much united with the 
muscle next to be noticed in Hyzenas and in the Cat. 
The flecor sublimis digitorum is not blended with the palmaris 
longus, but is very small, and takes origin from part of the tendon 
of the flecor profundus, as also in the Civet. It goes to the four 
outer digits; and in Crocuta (where it seems yet more completely 
blended with the flexor profundus) it goes to the three middle digits *, 
the fifth being supplied by a minute separate muscle *; as also in the 
Civet, which Mr. Young (/.c. p. 172) compares with my and Murie’s 
“flexor brevis manus” of Hyraz’. 
The flexor profundus digitorum arises by five bellies, three from 
the condyle, one from the radius (as in the Cat), and one from the 
ulna. It has four origins in the Civet—1. condylo-ulnar, 2. condylo- 
radial, 3. radial, and 4, ulnar. 
The flexor carpi ulnaris is as in the Cat, except that the two 
heads soon unite to form one belly. In the Civet the muscle is 
double, one part arising from the condyle and one from the olecra-

4 In Hyena striata the accessory slips are altogether tendinous. 
5 Tt arises in the Civet from the annular ligament, pisiforme, and tendon of 
palmaris longus. See also Cuvier’s ‘ Planches,’ pl. 126. fig. 2, x, o.
