A NEW NATALINE BAT FROM THE BAHAMAS. 

 BY GERRIT S. MILLER, JR. 



[By permission of the Secretary of the Smithsonian Institution.] 



While accompanying the Bahama Expedition of the Geo 

 graphical Society of Baltimore, Mr. J. H. Riley obtained four 

 specimens of a nataline bat easily distinguishable from the 

 species hitherto known. They were taken in a cave near Sandy 

 Point, at the southwest corner of Watlings Island. The animal 

 may be known as: 



Chilonatalus tumidifrons, sp. nov. 



Type. Adult male (in alcohol) No. 122,024 United States National 

 Museum. Collected on Watlings Island, Bahamas, July 12, 1903, by 

 J. H. Riley. Original number 157. 



Characters. Not as small as Chilonatalus micropus and C. brevimanus, 

 but forearm of about the same length as in the related species. Frontal 

 gland extending from middle of forehead nearly to end of muzzle, and 

 rising 5 mm. above level of eye. Skull and teeth essentially as in Chilo 

 natalus micropus, but much less diminutive in size. 



External form. Except for the slight difference in size, the external ap 

 pearance of Chilonatalus tumidifrons is closely similar to that of C. mi 

 cropus. The forearm, however, is relatively shorter, and the ears are 

 more evenly rounded off above. Lips and muzzle as in the related spe-
