 By Knud Andersen. 



Full descriptions of the species and subspecies briefly 

 diagnosed in this paper will appear in the new edition of the 

 British Museum ' Catalogue of Cliiroptera ' now under 

 preparation. 



Pteropus hypomelanus canus, subsp. n. 



Teeth averaging larger than in any other race of the 

 species, except Pt. h. lepidus. Back, in the normal pale- 

 coloured phase, pale mouse-grey, lightening to silvery whitish 

 grey on rump, and with or without a distinct buffy suffusion ; 

 mantle some shade of hazel or chestnut ; head similar to or 

 brighter than mantle. Size as in lepidus. 



Type. $ ad. skin and skull, Pulo Pandak, North Natuna 

 Islands, Sept. 1894 ; collected by Oh. Hose ; presented by 

 the Tring Museum; B.M. 95. 11. 8. 3. 



Specimens examined. Four, from the collections of the 

 U.S. National (one *) and British Museums. 



Range. North Natuna Islands : Pulo Panjang, P. Pandak, 

 P. Laut. 



Remarks. — This form is readily distinguished from Pt. h. 

 lepidus by the conspicuously brighter tinge of the mantle 

 and head. 



Pteropus hypomelanus annectens, subsp. n. 



Teeth not averaging larger than usual. Normal pale- 

 coloured phase rather similar in colour to corresponding phase 

 of Pt. h. lepidus, but generally more strongly suffused with 

 golden ochraceous or paler or darker Prout's brown on back, 

 and with brighter mantle and head. Forearm 130-134 mm. 



Type. Imm. ale. and skull, Sirhassen, South Natunas, 

 collected by A. Everett; B.M. 94. 9. 28. 25. 



Specimens examined. Five, from the collections of the U.S. 

 National (three j") and British Museums. 



Range. Sirhassen, South Natuna Islands. 



Remarks. — In characters as in habitat this race seems to 

 occupy an intermediate position between Pt. h. lepidus 

 (Tambelan Islands) and Pt. h. tomesi (Borneo) ; in the size 

 of the teeth it accords with the latter form, in the colour of 



* U.S. N. M. 1047:57; Pulo Laut, X. Natunas. 

 f U.S. X. M. 104732-34 : Sirhassen.
