CoccoTHRAUSTES. FringillidcB with mandibles of great thickness 



for the purpose of ci'ushing seeds with hard shells. 

 Pyrrhula. Fringillida with mandibles adapted to the habit of 



biting off, and feeding upon, the young buds of trees. 

 Passer. Fringillida with mandibles of medium strength, suited 



to a varied diet of seeds, vegetables, and coleoptera. 

 Fringilla. Fringillida with mandibles of medium strength, 



fitted for a regime of seeds, rather varied in their kind and 



size. 

 Cannabina. FringillidcE with mandibles produced to an acute

XL. — Note on the Birds of Prey of New Guinea. 

 By Philip Lutley Sclater. 



(Plate X.) 



In my Catalogue of the Mammals and Birds of New Guinea, 

 published in the 'Journal of the Proceedings of the Linnean 

 Society' (Zool. vol. ii. p. 15-i), I was able to enumerate only 

 four Diurnal and two Nocturnal Accijntres as known to occur in 

 that country. Mr. Wallace's researches at Havre Dorey have 

 since added two more to the list, so that we now know of the 

 following eight species of Raptorial birds inhabiting New 

 Guinea : — 



1. Ichthyaetus leucogaster. 5. Astnr nova hollandits. 



2. Haliastur leucosternus. 6. Accipiter poliocephalus. 



3. Henicopernis longicauda. 7. Spiloglaux humeralis. 



4. Baza stenozona. 8. Spiloglaux theomacha. 



Of these eight birds, Ichthyaetus leucogaster, Haliastur leuco- 

 stei'nus, and Astur nova hullnndia are well known as Australian 

 species, and have a somewhat extended geographical distribu- 

 tion ; the remaining five, as far as has been hitherto recorded, 

 have only been met with in New Guinea and the Aru Islands, 

 which belong essentially to the same fauna, — a further testimony, 

 if any additional witness were necessary, to the peculiarities of 

 this zoology.
