Diagnosis. — Premolars and molars simple. Smallest species : 

 forearm about 80 mm. Hah. Jf.W. New Guinea. 



Slcull and dentition, — Cranial characters not peculiar. Upper 

 canines slenderer at base than in other species, cingulum narrower. 

 Premolars and molars essentially Ronsettine in structure : no 

 distinct antero- internal basal cusp (a faint indication may be seen 

 in p"*), no distinct posterior basal ledge (in one of the specimens 

 examined a slight notch at postero-external base of p^ and m^ 

 evidently indicating an initial stage toward the development of a 

 ])osterior basal ledge), no trace whatever of surface-ridges. 



External characters. — Essentially typical. Ears distinctly at- 

 tenuated above, though rather less abruptly so than in other species, 

 and with the narrow terminal portion relatively somewhat shorter; 

 extreme tip uarrowly rounded off. Tibia conspicuously shorter 

 than usual, only ^ (in other species from f to nearly twice) the 

 length of the hind foot with claws. Terminal phalange.s of third, 

 fourth, and fifth digits relatively shorter. Membranes from base or 

 basal half of first phalanx of first toe. General size considerably
