Fig. 1. Lateral view (left) and dorsal view (right) of the holotype of Myotis elegans, × 2.

Remarks.—The longitudinal dorsal profile of the skull and the deeply notched posterior border of P4 seem to be distinctive of elegans. When the characters of elegans first were tabulated it was felt that it probably was only subspecifically different from some previously named species. But further study of the distinctive characters indicates that they are outside the range of variation of any near relative of elegans and it, therefore, is here accorded specific rank.

Material examined.—Known only from the holotype.
