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 Hyaenas 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 Hyaenas it 

 only goes to the 4th and 5 th \ 



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 Hyaenas), and as 

 inserted into a sesamoid at the base of the first metacarpal according 

 to Macalister ", and exclusively into the metacarpal of the poUex ac- 

 cording to Mr. Young. 



The extensores indicts 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 Hyaenas, but present 

 in the Civet, where it goes to the pollex and index. 



The pronator teres is as in 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 Hyaenas. 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 Hyaenas. 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 Hyaenas and in the Cat. 



The flexor sublimis digitorum is not blended with the palmaris 

 longus, but is very small, and takes origin from part of the tendon 

 of the flexor 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 {I.e. p. 172) compares with my and Murie's 

 " flexor brevis manus " of Hyrax *. 



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-

* In Hyana striata the accessory slips are altogether tendinous. 



^ It arises in the Civet from the annular ligament, pisiforme, and tendon of 

 palmaris longus. See also Cuvier's ' Planches,' pi. 126. fig. 2, k, a.
