The tikiill, as compared with that of P. Leinleri, is sliL!;htly 

 smaUer, loss massive, and relatively Ioniser ami narrower, 

 characters which, altlioni^h quite apparent to the oye, do not 

 stand out so clearly when exj)ressed in words. It is not at 

 all lilce the much smaller P. azoreum^ Thomas, with its 

 somewhat inflated cranium and depressed nasal region. 



The dimensions in millimetres of a female (in spirit) are as 

 follows : — 



Head and body 55; ear 12; tragus 4; frreatest expanse

Hah. Madeira. 



This species is evidently the representative of P. Leisleri 

 in Madeira, and it is remarkable how different it is from its 

 neighbour P. nzoreuni of the Azores. It is described from 

 specimens in the li. F. Tomes collection procured by Mison. 

 According to the custom of his day, Tomes identified his 

 specimens with P. Leisleri^ from which species, however, it 

 is fdearly differentiated by its characteristic skull. 



Tlie type is no. I of the Tomes collection in the British 

 l^Iuseum (a female). 



2. Pterygistes montanus^ sp. n. 



As regards general size, coloration, and characters, so far 

 as they can be ascertained from a specimen long in spirit, this 

 bat is very similar to P. Leisleri; but the remarkably lar^e 

 and massive skull, the big teeth, and somewhat /Joc/«/a-like 

 dentition mark it as one of the most distinct members of the 

 Leisleri group, occupying a position at the head and opposite 

 end of the .series to tliat occupied by P. azoreum at the foot. 



The skull is remarkably strongly built and massive ; the 

 lambdoid crests are well developed, the sagittal less so; the 

 teeth iire very large, except the small anterior upper premolar, 

 which is relatively inconspicuous and recalls that of n»cliila. 



The dimensions of the type (a female in si)irit) are as 

 follows : — 



Head and body 60 ; car 1 2 ; tragii.^ G ; thumb and claw 6"5 ;
