Prontops Dobson, Catal. Chiropt. Brit Mus., p. 407 (part). Subgenus of Molossus. Type-species.—Promops ursinm Gervais=Molossus nasutus Spix. Geographic distribution.—Warmer parts of America, north to southern Mexico. Number of forms.—This genus as now restricted contains only the type species and Promops fosteri (Thomas). Characters.—Dentition as in Eumops, except that the upper inci- sors are not as high (barely one-half height of canine), the anterior upper premolar is re- duced to a mere structureless, often deciduous, spicule, the lower premolars are greatly crowded, their width notice- ably exceeding their length, and the upper molars lack all distinct trace of hypocones. Skull (fig. 48) differing con- spicuously from that of Eu- mops in its general shorter, broader, and more rounded outline, the presence of a high sagittal crest extending for- ward almost to level of lach- rymal region, the very marked shortening and deepening of the rostrum (horizontal dis- tance from orbit to nares scarcely half depth through lachrymal region), the slightly emarginate audital bullae (as in Molossus and Eumops), and the highly domed palate (antero-posterior concavity nearly as great as lateral). External form heavier and more robust than in Eumops. Ears short, rounded, arising from same point on forehead, extending barely to nostril when laid forward; keel low and rounded; anti- tragus very distinct, constricted at base, its substance noticeably thickened posteriorly; tragus minute, very slender though distinctly flattened. Muzzle pad very small but rather distinctly outlined, though without median ridge or horny processes; a keel-like ridge from immediately behind muzzle to point of origin of ears. Lips slightly expanded, scarcely wrinkled; spoon hairs small, forming a. Fig. 48.
