M. abductor hallucis ( fig. 19 )

ORIGIN: From a ridge on the plantar surface of the centrale.

INSERTION: Via a long tendon on the medial surface of the sesamoid that covers the metatarso­phalangeal joint of digit I.

REMARKS: I found this muscle in all of the study taxa except Condylura , Desmana , Galemys , Talpa , and Uropsilus . The homology of this muscle is unclear, and I follow Reed (1951) in using this name for it. Reed (1951) incorrectly claimed that it increases in size with increasing fossorial activity: it is well developed in Scapanus , but not in Parascalops or Scalopus , and it is apparently absent in Talpa .
