338 ON THE MYOLOGY OF THE EDENTATA. [Mar. 7, specimen of Myrmecophaga which Ave examined (11) there was a well-marked flexor brevis digitorum mantis, Avhich rose from the anterior annular ligament and was inserted into the middle pha­langes of the annularis and minimus. The same muscle with the same attachments was evidently present in Pouchet's specimen (12). An adductor pollicis was met with in this specimen, arising from the base of the second metacarpal, and was also present in (11) and (13). In all three specimens an abductor minimi digiti, arising from the pisiform, was also present. The dorsal interossei were arranged as in Man. W e were unable to examine the palmar interossei in our specimen, but in that described by Macalister (13) there were apparently two, belonging to the index and annularis respectively. In Tamandua (14) there were superficial adductors to the index, medius, and annularis, aud a pair of flexores breves to each functional digit. There were also abductor and flexor brevis pollicis. In Dasypus (22) there is an abductor and flexor brevis pollicis, an abductor minimi digiti, and a transverse adductor indicis arising from the heads of the metacarpals of the annularis and minimus. Interossei are inserted into the radial side of the index and medius, and others are represented by fibrous bands. In Manis (30) there were superficial adductors from the bases of the palmar side of the metacarpals to the index and minimus. There were also four dorsal interossei arranged as in Man, but no palmar interossei were present. In Oryeteropus (35, 36) there appear to have been superficial adductors for the index and minimus, an abductor minimi digiti, and paired flexores breves to all four digits. BIBLIOGRAPHY. I.
