Pipistrellus sturdeei, sp. n. 



A small species, with narrow delicate skull. 



Size small ; general build slender. Ears rather shorter 

 and rounder than those of the Japanese P. abramus, inner 

 margin rounded at base, but not prominently convex; tip 

 broadly rounded off; outer margin flattened above, slightly 

 convex below, with a well-marked anti-tragal lobule. Tragus 

 of the general type of that of ahramus, but shorter, its 

 broadest point opposite the lower third of its inner margin ; 

 breadth going about 1| in the length of the inner margin, 

 the latter straight ; tip rounded, outer margin evenly convex, 

 basal lobe sharply triangular. Wings to the base of the 

 toes. A narrow postcalcarial lobule. Tail of the usual 

 seven vertebra?, its extreme tip only projecting. 



Colour of fur blackish throughout; the wings dark brown, 

 without marked marginal lines. 



Skull not much shorter than that of F. ahramus, but 

 markedly narrower throughout. Muzzle and brain-case 

 smooth, rounded, the ridges little developed. Anterior
