WHIDDEN, HOWARD P., 2000, Comparative Myology of Moles and the Phylogeny of the Talpidae (Mammalia, Lipotyphla), American Museum Novitates 3294, pp. 1-53 : 25

M. dorsoepitrochlearis ( fig. 10 )

ORIGIN: From the surface of M. latissimus dorsi , just posterior to the insertion of that muscle on M. teres major .

INSERTION: Into fascia over the forearm flexors.

REMARKS: This muscle has the same general form in the 11 study taxa.

M. triceps brachii , caput lateralis ( figs. 9 and 11 )

ORIGIN: A superficial layer from the lateral surface of the greater tuberosity of the humerus adjacent to the deltoid process, and a deep layer from the posterior surface of the humerus and the underside of the greater tuberosity.

INSERTION: Both layers on the lateral side of the posterior crest of the olecranon.

REMARKS: This muscle has the same general form in Condylura , Neurotrichus , Parascalops , Scalopus , Scapanus , Talpa , Scaptonyx , and Urotrichus . In Desmana , Galemys , and Uropsilus , there is only one part to this muscle, corresponding to the superficial layer in the other taxa.
