Pteropus intermedium , sp. n. 



Allied to Pt. giganteus, but breast and belly seal -brown or 

 blackish like back. Forearm about 180 mm. 



Type. J ad. skin and skull, Amherst, near Moulmein ; 

 collected by W. Davison ; presented by A. O. Hume, Esq. ; 

 B.M. 85. 8. 1. 101. 



Remarks. — In skull and dentition this species is scarcely 

 distinguishable from Pt. giganteus; in all external characters, 

 except the colour of the breast and belly, it is similar to that 

 species, though apparently rather larger ; but it resembles 

 Pt. vampyrus in the blackish colour of the breast and belly. 

 From the geographically nearest race of Pt. vampyrus, viz. 

 I y t. v. malaccensis (see below), it is readily distinguished by 

 its much smaller size (forearm about 180 mm., against 200- 

 209) and by having the foreneck nearly as bright-coloured 

 as the mantle, in strong contrast to blackish breast and belly. 

 From the Siamese Pt. lylei (forearm 148-154 mm.) it differs 

 by its much larger size. 



Pteropus vampyrus malaccensis, subsp. n. 



Mantle bright-coloured, sharply contrasting with dark 

 back. Skull, total length 76 # 5-86*5 mm. ; forearm 200- 

 209 mm. 



Type. <$ ad. skin and skull, Kuala Tembeling, Pahang, 

 Malay Peninsula, 26th Aug. 1903; collected by H. C. 

 Robinson, Esq. ; B.M. 6. 10. 4. 7. 



Specimens examined. Nineteen, from the collections of the 

 Leyden (three, Sumatra ; one, Banka), U.S. National (three, 

 Linga Arch.*), and British Museums. 



Range. Malay Peninsula ; Sumatra; Linga Archipelago ; 

 Banka. 



Remarks. — The range of Pt. vampyrus, in its full specific 

 sense, covers almost exactly the Indo-Malayan subregion as 

 defined by Wallace ; only in the extreme south-east the 

 species crosses " Wallace's line " and extends to Timor. 

 Within this vast area Pt. vampyrus is differentiated into six 

 races. Three of these, viz. Pt. v. pluton (Bali and Lombok), 

 Pt. v. edulis (Savu and Timor), and Pt. v. lanensis (Philip- 

 pines), are " melanistic " races, i. e. the mantle i3 generally 

 blackish or Vandyck-brown, similar in colour to, or not 

 strongly contrasting with, the back. In the three other 

 races the mantle is generally some shade of buffy, much 

 paler than, and strongly contrasting with, the back ; of these, 



• U.S. N. M. 101590-91, 101593.
