' Tyjye Locality. — Jamaica. 



Distribution. — Jamaica. 



General Characters. — Size rather small; ears with the prominent 

 internal wing united with its fellow ; lower margin of chin-lappet 

 with two central projections ; labial fold very deeply cleft centrally. 



Head. — Broad, long and shallow. Ears very large, the lower 

 margins extending forward to the commissure, thus, with the ante- 

 rior trend of the internal connecting membrane, forming a cavity 

 in which is located the rather minute eye ; internal connecting 

 membrane carried forward and connecting with its fellow posterior 

 to the nasal region ; the apex of the ear mth. a concave emar- 

 gination ; internal ridge well developed, extending to the tip of the 

 ear, inferiorly rather deep, the tip broadly rounded ; antitragus 

 high, apex circular; tragus rather large, apically with an addi- 

 tional sublanceolate, subpetiolate process, inner border with a 

 median emargination, outer border inferiorly emarginate, centrally 

 with a rounded process. Eye with wart near both the anterior and 

 posterior corners. Nostrils opening in the lateral portions of a 

 fleshy disk, which has the superior margin concavely emarginate, 

 below which the didk bears a median ridge; nasal apertures sur- 

 rounded by slightly raised margins; the central formation laterally 

 flanked by rectangular fleshy processes; upper lip deeply notched 

 opposite the first upper premolar, an acute process projecting for- 

 ward from the commissure. Chin-lappet of lower lip subquadrate, 

 upper margin with a central concavity, lower margin with a pair of 

 small processes in the center ; surface papillose. Labial fold ample 

 extending much below the chin-lappet, deeply divided into four 

 portions by incisions, one median and two lateral. 



Limbs. — Forearm moderately long, considerably bowed; third 

 finger rather long, very slender, the latter character applying to all 

 the digits ; thumb delicate. Femora, tibire and feet long and veiy 

 slender ; calcanea long, about equaling the tibiae. 



Membranes and Fur. — Membranes very thin and semi-trans- 

 parent, very finely tucked and wrinkled by cross nerves, the pattern 

 of the latter being very regular; propatagium large, the anterior 

 border totally free; uropatagium ample, extending (juite a distance
