probably do upon some future occasion. I think we may now con- 

 clude, from what I have adduced, that the bird purposely deposits 

 these bones as a nest ; and nothing can be better adapted, as a plat- 

 form, to defend the eggs from the damp earth. 



4. List of the Birds lately sent by Mr. A. R. Wallace 



FROM DOREY OR DoRERY, New GUINEA. By GEORGE 



Robert Gray, F.L.S., etc. 



[The * indicates those that are for the first time recorded from Dorery, New 



Guinea.] 



Amongst the series of New Guinea birds received from that inde- 

 fatigable naturalist and collector Mr. A. R. Wallace, are several 

 which prove of so great an interest, that I am induced to draw up 

 the following list of them, as an Appendix to my paper on Aru and 

 Ke Island-Birds, which I laid before the Society the 23rd of March, 

 1858. (Proc. Zool. Soc. 1858, p. 169.)* 



Falconid^:. 



1. Haliastur leucosternus (Gm.). 



2. *Baza stenozona, G. R. Gr. P. Z. S. 1858, p. 169. 



3. ASTUR LONGI CAUDA, LeSS. 



The collection contains a female specimen of this rare bird, which 

 has hitherto been supposed to belong to the subfamily Accipitrince ; 

 but the examination of this example proves that it would be more 

 correctly placed in that of Milvince, as it possesses all the characters 

 which are essential to that group. It forms part of the genus Pernis ; 

 but as it exhibits some slight differences in the wings, &c, from the 

 type of the genus, I have ventured to propose the subgeneric appel- 

 lation of Henicopernis, instead of adopting Bcedalion (Dcedalia), as 

 suggested by Prince C. L. Bonaparte, because the latter word was 

 long since given by Savigny as a more classical term for that of 

 Astur. It should therefore stand thus — 



Pernis (Henicopernis) longicauda, G. R. Gr. 

 2 26" 6"'. 



Beneath the body white, slightly tinged with rufous, and longi- 

 tudinally streaked with blackish-brown. 



4. *Accipiter poliocephalus, G. R. Gr. P. Z. S. 1858, p. 1/0. 

 (5 juv. Greyish brown, more or less margined with rufous ; tail 



greyish-brown, with narrow bands of black ; under surface White, 

 marked down the middle of each feather with rufous, enlarged in 

 some at the tip ; thighs and under wing-coverts rufous ; bill black ; 

 feet yellow.
