Sep- tember 30, 1903 (genus). Type-species.—Natalus micropus Dobson. Geographic distribution.—Bahama Islands, Greater Antilles (Cuba, Jamaica), and Old Providence Island, Caribbean Sea. Number of forms.—Three species of Chilonataluu are now recognized. Characters.—Differs from Natalus in the presence of a ridge-like dermal out- growth on muzzle, suggesting a rudimen- tary noseleaf, and another on chin, pro- ducing in profile a double-lipped aspect; males, with large glandular swelling be- tween and in front of eyes. Skull (fig. 27) like that of Natalus, but with rostrum relatively longer, more slender, and more depressed posteriorly. Species examined.—Chilonatalus micro- pus (Dobson), C. brevimanus (Miller), and C. tumidifrons (Miller).. Remarks.—Although distinejuished Fig. 27.—Chilonatalus micbopus. x2f. chiefly by external characters, this genus differs from Natalus in the excessively attenuate, flattened rostrum. It contains the smallest known numbers of the family, Nyctiellus lepidus excepted. Genus NYCMELLUS Gervais. 1855. Nyctiellus Gebvais, Expgd. du Comte de Castelnau, Zool., Mamm., p. 84. 1866.
