PHYLLOSTOMID^. 



its extremity four well-defined cutaneous tooth-like processes pro- 

 ject upwards, one from the sharply cut upper margin of each 

 nostril, and one larger on each side (Plate XXIII. fig. 1). Lower 

 lip much expanded outwards, with a thin free edge broader in front, 

 the surface opposite the canines covered with wart-like papUlse ; 

 from the chin an underlying cutaneous expansion is directed hori- 

 zontally outwards, and almost touches the lower free margin of the 

 lip ; the inferior surface of this expansion is marked by three parallel 

 ridges in this and in all other known species (Plate XXIII. fig. 1). 



"Wings from the inner side of the lower third of the tibia; and 

 from the calcanea. 



Above greyish brown ; beneath, much paler, almost white. 



Brain-case vaulted, and considerably raised above the face-line, but 

 the cranio-facial axis is almost in the same right line ; frontal bones 

 flattened, but not expanded laterally ; no postorbital processes ; 

 zygomata short and very slender ; nasal opening small, directed 

 forwards ; premaxillary bones united, but slender ; central upper 

 incisors triangular in outline, the apes at the root, the base deeply 

 notched, forming the cutting-edge ; outer ujjper incisors very small, 

 with a broad, base and a single oblique acutely pointed cusp directed 

 forwards and inwards ; first upper premolar small, with a single 

 acutely pointed vertically directed cusp ; second upper premolar 

 equalling the canine in cross section at the base, its acutely pointed 

 cusp slightly exceeding the molars ; molars with well-developed 

 W-shaped cusps, the last molar half the antepenultimate molar ; 

 lower incisors trifid, equal, each tooth triangular in cross section at 

 the base, the apex of the triangle inwards ; first and third lower 

 premolars equal in vertical extent, the cingulum of the first more 

 developed upwards : second lower premolar very small, internal to 

 the tooth-row, not visible from withoiit ; the three lower molars 

 nearly equal in size.

Hub. AntiUean Subregion (Cuba, Hayti, Jamaica). 



This species is easily distinguished from all other known species 

 by the small erect cutaneous processes above the nostrils, and very 

 acute-angled notch terminating the emargination on the outer side 

 of the ear.
