118 PROCEEDINGS OF THE ACADEMY OF [1894. 



Hah. Bristow Isl., New Guinea (Saunders). Montevideo (Coll. 

 A. N. S. Phila.) 



The &ro«'»-black color of the plumage and the uniform white of 

 the crown, sharply contrasted with the brown of the neck easily dis- 

 tinguish this species. Mr. Saunders' figure (P. Z. S., 1876, PI. LXI, 

 Fig. 3) is an excellent representation of this bird, although in the 

 specimens before me the white of the head does not extend quite so far 

 back. 



Description. — General color above and below uniform sooty broivn- 

 black, primaries black, lores, immediately in front of the eyes rather 

 blacker than the sides of the head. 



Crown from base of bill to occiput nearly pure white with the line of 

 demarkation between the white and general color of the hind neck very 

 sharply defined. Wing 8 -75 inch, culmen 1-80. 



Type. — No. 5,027 collection Acad. Nat.Sci. Philada. (from the col- 

 lection of the Duke of Rivoli) " Mer de Montevideo."
