TTEEOPUS ARGENTATUS. ] !J7 



Gray), while the name Pt. affinis, Gray, appears to have escaped liis 

 attention. The skull figured by Matschie (/. s. c.) under the name 

 Pt. caniceps is that of a young t'eniale of tiiis species collected in 

 Batcliian by Prof. E. v. Martens (Berlin Museum, no. ?A72). — 

 Tiic name Pi. ht/pomelanns in Jeutink's 'Catalogue osteologiqiie ' 

 and 'Catalogue systeinatiquc' (l. s. c.) covers three species, Pt. hijpo- 

 melanus, cankrps, and palU<las. 



Jteinarks. — Pt. atniceps is readily distinguished from Pt. hypo- 

 mdatins by its heavier roslrura, broader palate, larger orbits, 

 heavier cheek-teeth, and much larger and more narrowly pointed 

 ears. The colour of the fur, though very variable individually, 

 never (so far as the available material goes) closely approaches that 

 of any form oi Pt. liypomelanus. — From tbe species of the Acerodon 

 machloti group, to which it bears much external resemblance, 

 Pt. caniceps differs widely in the structure of the clicek-tecth 

 (no trace of inner basal ledge). — Its differences from Pf. dohs<>id 

 have been summed up in the diagnosis above.

Diagnosis. — Similar to Pt. canictps. but orbits smaller, cheek- 

 teeth much smaller, fur longer. Upper side of body dark brown 

 heavily sprinkled with longer yellowish hairs, under side russe'c 

 mixed with longer huffy hairs ; mantle and head buffy or ochra- 

 ceous-buffy, forcneck tawny. Probably rather larger than 

 Pt. caniceps. Hah. Uncertain ('? Amboina). 



Slcull and teeth. — Type .skull defective and not full-grown ; 

 orbits smaller, palate relatively narrower than in Pt. caniceps. — 

 Check-teeth much smaller than in Pt. caniceps, but not differing
