Pteropiis baveanus, Miller. Five. Biol. Soc. Waah. six. p. G3 (1 M.iy- 

 lUOtJ: ISiiwean). 



DUif/nosis. — Skull typical Pberopine. Cheek-teeth short and 

 Itroad ; posterior ledges obsolescent in p^ and jj^, entirely unde- 

 veloped in p^ and p^. Ears moderate, broad, exposed, tip rather 

 broadlv rounded olt. Tibia naked above. Fur of back short, 

 adpressed. General colour blackish above and beneath, thinly 

 sprinkled with greyish-white or greyish-buft'y ; back and anal 

 region often washed with vaudyck-brown or dark mars-brown ; 

 mantle varying from pale hazel to deep chestnut. Forearm 152-5- 

 160 mm. Hah. Bawean I. 



S?i-ull. — Similar to that of Pt. hmMinclamis, but somewhat larger, 

 with heavier and particularly deeper rostrum, and relatively sliglitly 

 larger orbits. Coronoid sloping; coronoid height of mandible much 

 less than c-ra3 ; condyle above level of alveolar line. 



Teeth. — Upper canines strong, slightly recurved or nearly straight; 

 median keel on hinder face sharply projecting ; cingulum well 

 defined but narrow, p' rudimentary, terete, deciduous. Premolars 

 and molars above and below markedly broader than in Pt. fij/jio- 

 melanus. Posterior ledge of p^ very short or obsolescent ; somc- 

 times a faint trace of the postero-external notch is detectable. In 

 p' the ledge is entirely undeveloped ; posterior margin of tooth 

 generally conspicuously oblique. Owing to large width of cheek- 

 teeth and shortness or absence of posterior ledges, the basal outline 

 of p'' and p' is subsquarish. m' simple, m'^ larger than va^. — 

 i , once and a half, sometimes nearly twice the bulk of i^. Cingulum 

 oV lower canines narrow. Pj about twice the size of i,. Posterior 

 ledge of y).j very short, generally not distinctly marked off from 

 tooth : ledge of p^ undeveloped, m^ and m^ simple, m^ usually 

 slightly larger than p^. 



Ears (dried skins). — Apparently not differing essentially in form 

 and relative size from those of Pt. hj/pomel emits. Not abruptly 

 narrowed above, tip rather broadly rounded off. 



Winc/s. — ilembranes about IS mm. apart at origin from back. 



Pfir. — Short and closely adpressed on back. Length of fur, back 

 and belly about 10-12, mantle 12-14 mm. Distribution of fur as 

 in Pt. liypomelanus. 



Colour. — Six paratvpes of Pt. haveamis, male and females, adult and 

 immature, skins, July : — Back and rump seal-brown, with or without 

 a distinct wash of dark vandyck-brown, in some specimens thinly, in 

 others more conspicuously sprinkled with silvery gre3-ish-white hairs. 



Breast, bellv, and flanks in most specimens blackish seal-brown, 



sometimes sliglitly, often more thickly sprinkled with silvery 

 greyish-white or greyish-buffy hairs ; anal region in some specimens 

 strongly suffused with vandyck-brown or dark mars-brown ; in one 

 specimen this suffusion extends over the belly and breast, every- 

 where considerably clouded with tlie general seal-brown colour of 

 the underparts. — Mantle varying from pale ha/.el or yellowish 

 einnamon-riifous to deep chestnut with a tinge of maroon ; colour 

 darkening on sides of neck, and passing on forcneck into blackish
