THE FAMILIES AND GENERA OP BATS. 149 



groove extending without break from last molar to last premolar, in- 

 clusive. Protocone low and long, occupying the entire inner border 

 of crown. Paracone and metacone low but distinct, their commissure 

 deeply concave. A faintly defined cingulum extends along outer edge 

 of tooth. Second molar smaller than first; third with about one- 

 third the crown area of second, its protocone and median groove dis- 

 tinct, its outer cusps barely indicated, though present. First and sec- 

 ond lower molars with median groove well developed, but less distinct 

 and continuous from one tooth to the next than in upper molars; 

 m 1 with paraconid low and hypoconid practically absent, but with 

 protoconid, metaconid, and entoconid well developed ; m 2 with dis- 

 tinct metaconid and protoconid exactly opposite each other at anterior 

 corners of crown, and low entoconid at posterior inner corner, but 

 hypoconid barely, if at all, indicated. Third lower molar with about 

 one-third the- crown area of second; it has two rather distinct cusps 

 in position of protoconid and metaconid. Skull showing no special 

 peculiarities, the braincase moderately high and with fairly devel- 

 oped sagittal crest, the rostrum somewhat more than half as long as 

 braincase, its greatest interorbital width slightly more than depth in 

 same region, and about equal to distance from incipient postorbital 

 process to canine. Nares slightly extended backward by a squarish 

 emargination more than half as wide as nasal aperture. Audital 

 bullae small, covering less than half surface of cochleae. Noseleaf 

 and ears normal. Tail absent. Interfemoral membrane moderately 

 developed. Calcar present, though small. In males there is a con- 

 spicuous tuft of stiff, modified hairs at front of shoulder similar to 

 the epaulettes of Epomophorus.
