Figure 7 - Posterior views of the basioccipital (view through the foramen magnum) in Sturnira bakeri (A, QCAZ 14635 ♀) and Sturnira luisi (B, ROM 104204 ♂) illustrating taxonomic differences in the degree of development of the clinoid processes. In Sturnira bakeri the clinoid processes are well developed (arrow). In Sturnira luisi, however, the clinoid processes are absent (arrow).
