Itt'iii a //*. -(fhmKophaga elonyata differs conspicuously from (*. lomji- 

 >W/v'.v in its paler color, particularly on the ventral surface. The cra 

 nial characters are equally distinctive. In one specimen (Xo. 101,S.~)."iV 

 the third upper molar is absent on both sides. 



Leptonycteris curasoae sp. nov. 



Type- adult male (in alcohol) Xo. 101,8.11 United Stales X'ational .Mu 

 seum, collected at Curacao, West Indies. 



Character*. Closely related to the Mexican Leptonyeteri* niralix (Saus- 

 sure) but color darker, and interfemoral membrane narrower and less 

 hairy. Upper inciwrtt equally xpaced and more projecting than in the 

 Mexican species. Second lower premolar slightly but distinctly cresren- 

 tic. 



Earn. The ears ace broad and short, laid forward they extend to an 

 terior canthus of eye. Anterior border of conch nearly straight and al 

 most horizontal through proximal .1 mm., then very abruptly convex., 

 Beyond this convexity it is again straight for about .1 mm. below rather 

 narrowly rounded tip. The two straight areas are nearly perpendicular 

 to each other. Posterior border slightly concave below tip, then mod 

 erately convex to faintly marked notch at upper edge of antitragus. 

 Ant i tragus small and ill denned, its substance distinctly thickened. The 

 slightly concave anterior border terminates abruptly a little in advance 

 of anterior base of. ear, and 7 mm. behind angle of mouth. Outer sur 

 face of ear smooth and naked except at extreme base, where it is cov 

 ered with fur similar to that of head. Inner surface slightly papillose 

 and sprinkled with inconspicuous hairs. Four or five very indistinct 

 cross ridges on inner surface of conch .near middle of posterior border. 

 Tragus upright, much thickened along anterior border. Anterior 

 border straight to slight subtermirial concavity. Point blunt. Posterior 

 border irregular, but without distinct projections. Thrqugh anterior 

 base the width of tragus is equal to 'one half anterior border. 



Muzzle and chin. Noseleaf diamond shaped, the lower portion bounded 

 by the oblique nostrils, the upper and slightly larger portion erect and 

 free. Lips below and at sides of nostrils tumid, this swollen area ex 

 tending back on each side immediately behind n;>seleaf nearly to median 

 line and separated posteriorly from noseleal' by a distinct, broadly V- 

 shaped groove. 



Chin divided by a deep groove, narrow below, wide above, iis edges ir 

 regularly tuberculate. 



Membrane*. The membranes are thick rough and leathery: the wings 

 and propatagium broad and ample; the uropatagium greatly reduced (only 

 4 mm. wide at middle). Propatagium extending as a broad fold along 

 forearm to include metacarpal of thumb. The me:nbranes are essen 

 tially naked.
