M. spinodeltoideus ( figs. 9 and 10 )

ORIGIN: From a tuberosity at the vertebral end of the scapular spine, and from the length of the scapular spine.

INSERTION: On the deltoid process of the humerus.

REMARKS: This muscle has the same general form in the 11 study taxa. It is particularly well developed in Condylura , Galemys , and Uropsilus . Campbell (1939) and Reed (1951) discussed the problem of determining the homology of this muscle: Mm. spinodeltoideus and teres minor have similar topographic positions and innervations, and when one is missing it is impossible to be certain of the identity of the remaining muscle. I follow Reed in using the name spinodeltoideus for this muscle.
