X. The Ptehopcs co.WiPiciLi.Ari.'s grocp. 



S/jecies. — Pt. chrj/sancfu'ii, conspicillatnx, ocularis. 



llangei — Moluccas, New Guinea, N. Australia. 



General charadcrs. — Skull as iu the Pt. alecto group, but heavier, 

 and with unusually stron"; crests. Teeth relatively larger, but not 

 differing in structure. Ears slightly larger, tip narrowly rounded 

 otl'; interfemoral short or obsolescent in centre ; length and dis- 

 tribution of fur as in Ft. alecto. Colour blackish above and beneath, 

 with strongly contrasting light yellowish mantle and occiput; often 

 pale spectacles. Sexual differentiaticni as in Pt. alecto. Size 

 merliuni or large (forearm 1:35-181 ram.). 



Differentiation of species. — Pt. chri/sauchen (Gilolo group, N.W. 

 New Guinea) and Pt. consiticillatus (S.E. New Guinea, N. Aus- 

 tralia) are geminate species; the latter differs from the former in 

 the slightly weaker denlition and pronounced pale Sj>ectacles, but 

 traces of spectacles are sometimes easily detectable in Pt. clirys- 

 Huchen. In relatively strong coutrast to these two very closely 

 related forms stands the much smaller Ceram species, Pt. ocularis. 

 Affinities of group. — The Pt. consj>icillatns replaces the Pt. alecto 

 group iu the Moluccas and Xew Guinea. The only differential 

 characters, as compared with the alecto group, are the rather larger 

 and more narrowly pointe<l ears, shorter interfemoral, and much 

 paler mantle.
