A New Bat (Myotis) From Mexico

It is a zoological book. A small-footed species having a short tail and small skull. Pelage on upper parts near (16' l) Prout's Brown (capitalized color terms after Ridgway, Color Standards and Color Nomenclature, Washington, D. C. , 1912), and more golden on underparts; ears pale brownish and flight-membranes only slightly darker; thumb small (7. 5 mm. including wrist); tragus slender but deeply notched. Longitudinal, dorsal profile of skull relatively straight but frontal region elevated from rostrum and lambdoidal region elevated from posterior part of parietal region; posterior margin of P4 (in occlusal view) notched. 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.
