It will thus be seen that in the Felidae, Viverridae, Hyaenidae, and Canidae the insertion of the pronator radii teres is usually into the middle of the radius or, in the Canidae, above that point, wrhile in the Ursidae, Procyonidae, and Mustelidae its insertion is more often into the lower end. Flexor carpi radialls.-This muscle, as usual in Mammals, is very constant; it rises from the internal condyle and is inserted into the base of the second metacarpal bone. The following are the only variations with which we have met in its attachments. In Cgncelurus (9) Ross (IV.) describes slips to the styloid process of the radius and to the trapezium. In Ursus americanus (50), Testut (XXIIT.) found it ending in tbe scapholunar. In Ursus arctos (47), Meckel (XXXIX.) notices its insertion into the 1st and 2nd metacarpal bones. Palmaris longus.-The palmaris longus in Carnivora is sometimes double ; when this happens we shall speak of an externus and internus. The former is the more constant and is closely connected with the flexor sublimis digitorum at its origin ; it spreads out in the palm to form the palmar fascia, and often has definite tendons running to the vaginal sheaths of the proximal phalanges. The palmaris longus internus appears to be a delamination from the flexor carpi ulnaris, and ends in the fascia over the pisiform bone. Among the Felidae the externus alone is present. In Felis tigris (3) it ends in five definite tendons, one for each digit. In F. leo (1) and F. pardus (4) Macalister describes a palmaris accessorius which rises from the main tendon a little above the wrist and is inserted into the pads over the 4th and 5th digits ; we find a similar muscle figured in Cuvier and Laurillard's plate of the lion's manus (V.), and in our opinion it is the same thing that we describe later under the name of flexor brevis digitorum manus. Among the Viverridae the externus and internus were present in Cryptoprocta (10), Genetta (18) (see fig. 9, p. 396), and Viverra, clvetta(12). In Herpestes (24) (see fig. 10, p. 404), V. civetta (14), and Paradoxurus (21) the externus alone was present, while in V. civetta (13) and Genetta (17) the internus was the only part found. In Proteles (25) the externus is distinct from the flexor sublimis digitorum, and there is no internus. Among the Hyaenidae the arrangement is the same in Hycena striata (26, 28) and H. crocuta (29), but in Meckel's specimen of the former animal (27) the muscle was closely blended with the flexor sublimis digitorum. In the Canidae we have records of seven specimens of Canis familiaris; in four of these the muscle is absent altogether (31, |
