Characters. — A. member of the sub-genus Spectrum as defined by Matschie. 

 Size very snaall (forearm 110 mm.) ; ears triangular-pointed ; colour tawny ; 

 the face and back strongly tinged with hair brown ; skull and teeth essen- 

 tially as in Pteropus lepidus, but much smaller. 



fur. — The fur of the back is silky in texture and closely appressed, tbe 

 individual hairs 10 — 12 mm. in length. On rump, thighs, and interfemoral 

 region it becomes distinctly woolly in texture, though less so than on other 

 parts of the body. It extends on leg to knee, below which there is a sparse 

 gprmkling of hairs along inner surface of tibia. Fur of shoulders, head, neck, 

 and underside of body loose and woolly in texture, therefore appearing much 

 Ioniser than that of back, though the length of the iadividual h;iirs is every- 

 where about the same. On under surface the fur extends about to knee and 

 elbow. Beyond the latter point it is continued as a sparse sprinkling of fine 

 hairs to middle of forearm. 



Membranes.— '^h.Q membranes show few peculiarities worthy of note. The 

 uropatagium is reduced to a mere rim, except along legs, where it is about VI 

 mm, in width. Between knee and body it is emirely concealed by the fur 

 above, but only partially below, Propatagium naked above, sprinkled 

 with fine hairs below. Wing membranes entirely naked above except for an 

 inconspicuous sprinkling of fine hairs close to body and along forearm. Below 

 they are scantily furred to line joining elbow and knee, also along forearm. 



Ears. — The ears are of moderate size, proportionally about as in Pteropus 

 lepidus, P. hypomelanus or P. nicoharicus and smaller than in P. meduis from 

 Tenasserim and Lower Siam. In form they are quite distinct from those of 

 any of the related species. Anterior border nearly straight from base to 

 about middle, then after a faint convexity again nearly straight to tip. 

 Extremity very narrowly rounded — less than 1 mm. in width. Posterior 

 border nearly straight from tip to a little above middle, then abruptly convex 

 for a distance of a few millimetres ; beyond this, nearly straight to slightly 

 above small but distinct antitragal lobe. At tip the anterior and posterior 

 borders form an angle of about 80°. The convexity of the posterior border 

 is so abrupt as to be almost angular. 



Oolciir. — Back hair brown, considerably darker than Ridgway's PI, III, Fig. 

 12, everywhere intermixed with ochraceous buff. Anteriorly the brown is 

 in excess of the buff, but posteriorly the buff becomes more conspicuous until 

 on rump it practically excludes the darker coloiar. The entire back is sprinkled 

 with silvery whitish hairs which are most conspicuous anteriorly. Mantle, head 

 and entire under parts ochraceous buff , brighter than that of back and strongly 

 tinged with tawny on chest, sides of neck, and middle of breast and belly. 

 Face, cheeks, and chin grizzled hair brown. Ears and membranes blackish. 



Skull and Teeth. — The skull and teeth show a remarkable likeness to those 

 of Pteropus lepidus, though immediately distinguishable by their much 

 smaller size. The interorbital region is, however, actually broader than in 

 the larger species, and the postorbital processes are more robt^st, Pterygoids
