Reithronycteris aphylla sp. nov. 



Type. — Adult $ (in alcohol) No. 9, Museum of the Institute of 

 Jamaica. Collected in Jamaica. No further history. 



Specific characters. — External appearance much as in Phyllonyc- 

 teris sezekorni Peters, 7 but muzzle conspicuously broader and termi- 

 nating in a disc-shaped rudimentary nose leaf like that of Brachy- 

 phylla cavemarum. Feet relatively larger thau in Phyllonycteris 

 sezekorni, and interfemoral membrane much less developed. Skull 

 broader and more heavily built than that of P. sezekorni aud lack- 

 ing the slender, but complete zygomatic arches often present in the 

 latter. 8 Teeth conspicuously shorter and broader than in Phyllo- 

 nycteris sezekorni; front lower molar very slightly larger than suc- 

 ceeding ones, not greatly elongated as in P. sezekorni. Color, of 

 specimen preserved in alcohol for an unknown period, light yellow- 

 ish brown. 



Fur and color. — The fur is short, about 6 mm. in length on mid- 

 dle of back, 4 mm. on belly ; it is very closely confined to the body, 

 barelv reaching the membranes. Color both above and below light 

 yellowish brown. Ears and membranes light brown. 



Ears. — The ears are short; when laid forward they reach just 

 beyond inner canthus of eye. Anterior border strongly convex from 

 base to a little above middle, then nearly straight to narrowly 

 rounded off tip. Posterior border slightly concave below tip, then 

 convex (the curve about the same as that of anterior border) to base. 

 Posteriorbase in line with upper lip, the distance from cornerof mouth 

 a little less than from the latter point to chin. A wart (concealed 

 by the hair) about as large as eye midway between corner of mouth 

 and posterior base of ear. Inner surface of ear with seven ill de- 

 fined cross ridges. 



Tragus a little less than half height of ear. Anterior border 

 gently and evenly convex from base to acicular tip. Posterior bor- 

 der with four deep scallops, subtending as many prominent tooth 

 like projections, of which the basal is less developed than the 

 others (it does not show in the view from which figure was taken). 



Feet. — Foot very large, fully three-fourths as long as tibia, the 

 toes deeply cleft and provided with large claws. No trace of calcar. 



7 This comparison is made with specimens from Nassau, Bahamas. These 

 may prove to be different from the typical Cuban form. 



5 Dobson, basing his description on Jamaican material, states that in Pliyllo- 

 nycteris the zygomatic arches are incomplete. This is not true of the Baha- 

 man specimens. There is little reason, however, to believe that the Jamai- 

 can Phyllonycteris with pointed nose leaf is the same as that found in the 

 Bahamas, and no certainty that either is true sezekorni.
