Nyctinomus antillularum sp. nov. 



Type.— Aduh male (iu alcohol), No. 113,188, United States 

 National Museum. Collected at Roseau, Dominica, W. I., 

 August 5, 1901, by H. Selwyn Branch. 



Characters. — In general similar to the common Nyctinoinus of 

 the Greater Antilles, but size even less, the length of forearm (iu 

 sixteen specimens) ranging from 36.5 mm. to 38.5 mm. 



Form, Color, etc. — In color and external form this species shows 

 no peculiarities as compared with the common representative of the 

 Ntjd'momm brasiliensis group, occurring in Cuba, Jamaica and 

 Porto Rico. As in the latter, the ears are relatively smaller than 

 those of the continental members of the genus, extending, when 

 laid forward, just to nostril instead of distinctly beyond end of 

 muzzle. The usual brown and red color phases are represented, 

 but as all but two of the specimens at hand have been preserved in 

 alcohol no exact comparison can be made. 



Skull and Teeth. — The skull and teeth do not differ appreciably 

 from those of Cuban specimens of the larger West Indian form. 

 The first lower premolar is very minute and without distinct 

 ciugidum.

 83; tail, 30; tibia, 12; foot, 6.6 (6); forearm, 47.4; thumb, 7;
