Fig. 8 in Phylogenetic Relationships Of Mormoopid Bats (Chiroptera: Mormoopidae) Based On Morphological Data

Fig. 8. Anterior views of the distal end of the humerus of (A) Pteronotus parnellii, (B) Pteronotus personatus, and (C) Mormoops megalophylla (redrawn from Vaughan and Bateman, 1970: fig. 5). Note the differences between Pteronotus and Mormoops in degree of development of the capitulum, location of the trochlea relative the shaft, and presence/absence of a deep groove between the trochlea and distal spinous process.
