The f,exor carpi radialis is as in the Cat. The pronator quadratus extends for about the lowest third of the length of the bones of the forearm (instead of half their length, as in the Cat). It extends for about the lowest quarter in the Civet, or a little more l. In Hyana striata it is large ; and in Crocuta it extends up the whole length of the bones of the forearm. It is very large in Hemigalea, and is inserted iuto the plate-like process of the radius. The lumbricales in the Genet are as in the Cat. In the Civet there are sometimes but three2, though there are four in Hyana and Crocuta. The flexor brevis poliicis arises by two heads in the Civet, and there is an opponens. There are no muscles furnished to the rudimentary pollex of the Hyanina. The abductor poliicis arises in the Civet from the ulnar ossicle, and has a long tendon. The abductor minimi digiti arises from the annular ligament and pisiform bone in the Civet, and it exists also in Crocuta. A second abductor arises in the Civet from inside the fifth metacarpal, and is inserted into the ulnar sesamoid of the fifth digit. There is also a second flexor brevis minimi digiti arising from the unciforme, and inserted beside the muscle previously mentioned. The interossei in the Civet are said to be3 as follows :-First, a (carpally arising) adductor indicis ; secondly, a metacarpal adductor indicis ; then an adductor annularis ; fourthly, an adductor minimi digiti: the foregoing are palmar interossei. The dorsal interossei are:-First, an abductor indicis; secondly, an abductor medii digiti; thirdly, an adductor medii digiti; fourthly an adductor annularis : these are all bicipital except the third. In Crocuta Dr. Watson says4:-"A deep set of interossei comprises eight fleshy bundles arranged in pairs, two to each metacarpal." "In addition to these paired muscles are two single ones (palmar interossei). These arise together from the bases of the third and fourth metacarpals. They are distributed to the middle and outermost digits respectively." Muscles of the Pelvic Limb. The gluteus maximus, gluteus medius, gluteus minimus, tensor vagina femoris, and biceps femoris are as in the Cat. The accessory biceps or tenuissimus is in the Genet as in the Cat5, except that it is slightly connected with the semitendinosus. In the Civet also it receives a slip, at its insertion, from the semi- 1 Mr. Young says "lower third" (I. c. p. 171). 2 Mr. Young (I. c p. 172) found four. 3 Macalister, Proc. Roy.
