Pipistrellus imbricatas and its Allies. 



So far as the Museum material shows, Java contains tliree 

 small species o£ Piphtrellus — P. tralatitius, P, imbricatus, 

 and a species allied to or identical with P. papuanu.f. 

 Putting aside the last-named, we find tliat P. imbricatus 

 differs from the common P. traladtiusj not only by its larger 

 ears and broader tragus, but, in the skull, by the peculiar 

 shortening- of its muzzle, the definite development of basial 

 ]jits, the extreme smallness of p^, which is only about one- 

 fourth tiie area of ^^, and by the fact that the posterior leg of 

 the Z on m^ projects further inwards compared to the anterior 

 one than it does in tralatitius. 



A scries of P. imbricatus from Java are all just of the same 

 size, and agreeclosely with the type ( B. M . no. 79. 11.21. lOS '") ; 

 and two specimens from Kangean, to the east of Madura, may 

 also be assigned to the same form. But a large series from Cen- 

 tral Borneo are uniformly much larger, and should evidently 

 be distinguished specifically. These two both have fairly dark 

 wings, while, on tlie other hand, the representative forms from 

 Sinnatra, Billiton, and Engano have wliitish or white wings; 

 but I have no specimens available, and cannot say if they 

 have other distinguishing marks. For these the name of 

 macrotis, Temm., is available, and I doubt if either vorder- 

 manni, Jent., from Billiton,or curtatus, Miller, from Engano, 

 are really distinct. It may be noted that Mr. Miller first 

 called liis Engano specimens imbricatus, and then, in 

 describing them as new, distinguished them from imbricatus 

 by the exact characters that separate imbricatus itself from 

 tralatitius — from which it seems probable that wiiatever 

 specimens of " imbricatus " he compared them with were 

 really examples of tralatitius. 



Pipistrellus kitckeneri, sp. n. 



Like P. imbricatus, but considerably larger. 

 Colour of fur a darker and riciier brown than iii imbri- 

 caius', under surface rather lighter. Wings smoky greyish, 



* On p. 380 of P. Z. S. 1909, B.M. no, 79. 11. 21. 124 was mentioned 

 as the type of P. tralatitius, Horsf. ; but further examination shows that 

 that specimen, although in the India jNluseum under the Jarae of trala- 

 fitius, is really an example of i7nf)ricatiis, while the other one mentioned, 

 the " Lowo-manir," ?«^ of Uobson's British Musoum Catalogue, was 

 received from Horsfield at an early date as traliditius, and should 

 therefore stand as the type. Its number is 62 a.
