Among the Mustelidae the muscle is very constant, being inserted into the first and second digits in Galictis vittata (63), Mustela putorius (65), M. folna (66), Ictonyx zorilla (69), /. libyca (70), Meles (71), Lutra vulgaris (74, 76), and L. cinerea (78). In Haughton's specimen of L. vulgaris (79) the insertion was into the second and third digits. Muscles of the Hand. Flexor brevis digitorum manus.-When this muscle is present in the Carnivora it rises from the annular ligament, pisiform bone, and palmar fascia, and occasionally from the lower part of the palmaris longus tendon. It is inserted into the vaginal sheath of the miuimus, or, if it is more fully developed, forms the flexor perforatus of that digit. Among the Felidae the muscle was Fig. 10. PALM. LONG. F.C.RffD, PBD.POi CMLN. 'BD.M/N.D/C. Manus of Herpestes griseus, showing single fl. br. dig. manus. present in F. leo (1 a), and apparently in Macalister's specimens Felis leo (1) and F. pardus (4), though in these it went to the fourth and fifth digits. In the Viverridae it was present and formed the flexor perforatus tendon to the minimus in Viverra civetta (12), Herpestes (24) (see fig. 10), and Genetta (17). In V. civetta (14) and Genetta (18) it ended in the vaginal sheath, and, in the latter animal, went to the fourth and fifth digits (see fig. 9, p. 396). Among the Hyaenidae it was present in Hycena crocuta (29), but not in H. striata (26,28). W e have no records of it among the Canidae or Ursidae, and it was certainly absent in our specimen of Canis familiaris (31). In the Procyonidae it seems very constant; it is present in Procyon lotor |
