Pterojius Icitcojd&rus. Tcuimiiick ; 18oJ3. — T}'i)0 localily, " iii- 

 cerfaiue, Ton presume I'une des lies Philippines." Tjpe, a young 

 ndult male (nearly full-grown, forearm 13U mm.), mounted, faded, 

 skull separate. 



Pterojivs chinensis. Gray ; 1870. — The type, an unregistered 

 sldn and skull, came to the iluseum from Robert Fortune, who, in 

 1843-45, travelled in the northern provinces of China as a collector 

 for the Horticultural Society of London ; hence it was, very 

 naturally, believed by Gray to be from " China." But the fact 

 was overlooked that Fortune also made au excursion to Luzon 

 (Januarj- to early in March, 1845; see his 'Three Years' Wan- 

 derings in the I\orthern Provinces of China,' pp. 332-345, 1847) ; 

 when to this is added that no species of Pteropus is known to occur 

 in China, and that the type of Pt. chinensis differs in no noteworthy 

 character from that of Pt. leucopierns, there can be no reasonable 

 doubt that it was obtained by Fortune during his stay in Luzon.

{TypR o? Pt. chinensis, Gray.) 



K. The Pteropvs temmixcki group. 



Species. — Pt. teniminchi, capistratus, personatus. 



liange. — Austro-Malaya : Celebes, Timor, Moluccas, Bismarck 

 Archipelago. 



General characters. — Skull delicately built, rostrum short and 

 slender, orbits unusually large (diameter greater than lachrvmal 

 width of skull), postorbital much greater than interorbital width, 

 sagittal crest undeveloped or low, coronoid process of mandible 

 sloping. Dentition weak, sometimes excessively weak; posterior 

 basal ledges of premolars distinct but short. Ears small, rather 

 broadly rounded off above ; tibia hairy above. Colour peculiar : 

 silvery buffy or silvery whitish, with concealed bases of hairs 

 strongly contrasting seal-brown ; mantle generally golden buffy ; 

 head sometimes with dark longitudinal stripes. Males without 

 glandular neck-tufts. Size very small (forearm 8G-116 mm.). 



Differentiation of species. — The three species differ chiefly in den- 

 tition, the colour of the head, and in size. In Pt. temmincJci (Timor 

 and Amboina groups) and Pt. capistratus (Bismarck Archipelago) 

 the teeth are unmodified in size, in Pt.personatas (Celebes, Moluccas) 

 excessively reduced. In IH. temminchi the head is uniform in colour ; 

 Pt. capistratus and personatus are unique in the genus in having the 

 head marked with broad longitudinal dark brown stripes, somewhat 

 different in number and arrangement in the two species (in all 

 forms of this group the fur, though superficially unusually pale, 

 is contrasting seal-brown at base; the peculiar head-stripes in 

 Pt. capistratus and personatus arc produced by the seal-brown 

 colour, in certain sharply deiined longitudinal areas on the head,
