Pipistrellus iinbiiciitus and its Allies. 



So far as the MiisiMun material shows, Java contains three 

 small species of Piiu'strellus — ./'. tral(iti(iit.<!, J*. intbn'catnH, 

 and a species allied to or identical with P. jyapuaiinn. 

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

 differs from the common P. tralntiliuH^ not only by its lar^or 

 ears and broader trai^us, but, in tlie skull, by the peculiar 

 shorteniii*:^ of its muzzle, the detinite devc'lopm(3nt of basial 

 pits, the rxtrome smallness of ;>', which is only about one- 

 fourth the area of <^, aiul by the tact that the posterior \<i^ of 

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

 one than it dot'S in tralatitius. 



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

 size, and agreeclosely with the type (B.M . no. 79. 11.21. 108*); 

 and two spcciniens from Kauj^ean, to the east of Madura, ni;iy 

 also be assigned to the same form. But a lar^jje series from Cen- 

 tral Borneo are unit'ormly much larger, and should evidently 

 be distinguished specifically. 'J'heso two both have fairly dark 

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

 Sumatia, Billiton, and Engano have whitish or wiiite wings; 

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

 have other distinguishing marks. For these the name of 

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

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

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

 called Ills Engano specimens imbricates, and then, in 

 describing them as new, distinguished them from imbricafus 

 by tlie exact characters that separate imbricatus itself from 

 tralatitius — from which it seems probable that whatever 

 specimens of '^imbricatus" he compared them with were, 

 really examples of tralatitius. 



Pipistrellus kitcheneri^ sp. n. 



Like P. imbricatus, but considoraldy larger. 

 Colour of fur a darker and richer brown than in inibri- 

 catus] under surface rather lighter. Wings smoky greyish, 



» On p. 380 of P. Z. S. 1000. B.M. no 70. 11. 21. 124 was nipntioncd 

 as the tvpe of P. tralatitius, llorsf. ; but further examination shows tiiat 

 that specimi^n, althou^rh in tlic India Museum under the name of tni/a- 

 titiiit, is really an example of imftricattis, while the other one mention-d, 

 the " Lowo-nianir,'' iv' of Dobson'a Jiritish Museum Cataloj^nie, was 

 received from Ilortifield at an early dat»^ as tralatitius, and should 

 therefore stand as tlie type. Its number is 02 a.
