338 ON THE MYOLOGY OF THE EDENTATA. [Mar. 7, 



specimen of AfynnecopJiaga which we examined (11) there was a 

 well-marked flexor brevis digitorum maniis, which rose from the 

 anterior annular hgament and was inserted into the middle pha- 

 langes 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 ypecimeu, 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. We 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 aunularis respectively. 

 In Tamaridua (14) there were superficial adductors to the index, 

 medius, and annularis, aud a pair of fiexores 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 ai-e 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 Orycteropus (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.
