Fteropus cagayamis, Mearns ; 1905. — Original description based 

 on three skins and skulls from Cagayan Sulu. Separated by 

 Mearns from Ft. hypomelanus chiefly on colour characters ; the 

 fikins "were temporarily preserved in formalin, but the colors 

 [Mearns writes] have not been materially changed." A comparison 

 of Mearns's two paratypes with a topotype in the British Museum 

 proves, beyond doubt, that the colour of the mantle in Mearns's 

 specimens has been considerably bleached by the preserving 

 fluid, which has also partly discoloured the membranes ; these 

 specimens have therefore been entirely excluded from the above 

 description of tho colours. According to Mearns, " the skull and 

 teeth of P. cayayanus are decidedly smaller than in Steere's 

 specimens from Panay, which he called ' Pteropus hypomelanus ' " ; 

 I am unable to see any difference in the size of the skull and 

 teeth between three specimens from Cagayan Sulu and five of 

 St;eere's specimens from Panay. 



Remarks. — Pt. h. cagayanus is intermediate between Pt.li. tomesi 

 (Borneo) and macassarlcus (Celebes) ; from either of these races it 

 can only be discriminated on average colour characters. It di&'ers 

 from tomesi in the rather brigliter mantle and rather more Front's 

 brown tinge of the back ; in both of these respects it agrees with, 

 or comes very near to, macassariciis, in which, however, the under- 

 parts average slightly paler.
