220 Mr. O. Thomas on a 



sijiJinionts, niul it was, of course, tlioui^lit at first that some 

 mistake had been made about the numbering ot" the skidls ; 

 but tliis theory falls to the ground now that three specimens 

 have been received all presenting the same characteristics. 



The species, by its cranial characters, is a most distinct 

 one, and is most interesting by the remarkable resemblance 

 above described. I have had great ])leasure in connecting 

 Avith it the name of jMrs. llinde, who has given much assist- 

 ance and interest in the preparation of her husband's coll^iction 

 of small mammals. 



XXXVII. — On a new Genus of Vesperti'lionine Bat from 

 New Guinea. By Oldfield Thomas. 



Among a small collection of mammals collected by Mr. H. S. 

 l\ohu in the Albert Edward ranges dividing German and 

 British New Guinea there occur a number of specimens of a 

 bat allied to Vespertilio, Ttjlonycten's, and Ilesperoptenus^ but 

 evidently distinct enough to require generic separation. 



Philetor, gen. nov. 



General facies rather as in Pterygistes. 



Incisors ^^. Premolars ^, as in Vesperdlio. Incisors 

 shaped as in Tyhnycteris. Lower premolars subequal, crushed 

 together. 



hjkull short, stumpy, rounded, with a large rounded brain- 

 case. Muzzle broad, with marked supraorbital projections. 



Muzzle much swollen. Wings proportionally small. 

 Fii'th fingers short, as in Pterygistes. Wings to the lower 

 end of the tibia. Penis with a bone, the glans peculiarly 

 modified, as are also the external female organs. 



Philetor Rohui, sp. n. 

 General appearance that of a small Pterygistes, the head 

 large, broad and flat, the fur short, and the wings propor- 

 tionally very small. Muzzle smoothly swollen ; the nostrils 

 far apart, their edges not projecting. Ears short, laid 

 forward they hardly reach halfway between eye and nostril ; 

 a small hem ending in a lobule at their inner bases ; inner 

 margin straight or slightly convex ; tip broadly rounded off; 

 outer margin slightly convex, then slightly concave, and 

 again slightly convex for its lower third, its base running 

 forwards to behind and below the angle of the mouth. 

 Tragus short, thickened, fleshy, its inner margin straight, its 

 outer slightly convex, with an inconspicuous basal lobule.
