members of the genus Astur in a restricted sense^ which we 

 unite with Accipiter. We therefore name the new bird 



" Accipiter (Astur) eudiabolus, sp. n. 



"Adult male. Upperside black, with a slaty tinge ; upper 

 wing-coverts widely margined with chestnut-rufous ; some 

 obsolete rufous margins to the scapulars and to some of the 

 feathers of the rump ; bases to the feathers brownish-grey, 

 pure white on the nape, which is not crested ; primaries 

 black, barred with smoky-brown, the bars becoming white 

 at the base. Underside white, broadly streaked with black, 

 cross-barred on the flanks; thighs and under tail-coverts 

 barred with black and chestnut-rufous.

*' Ohs. One specimen in the British Museum is like ours, 

 except that the whole underside is somewhat suffused and 

 spotted with rusty-chestnut. A second specimen in the 

 British Museum is exactly similar to ours. The chief 

 measurements are as follows : — 



" Two adults (apparently males) : wing 295 and 295 mm. ; 

 tail 215 and 212. 



*' One adult (apparently female) : wing 325 mm.; tail 250." 



Messrs. Rothschild and Hartert also communicated the 

 following note : — 



We have in the Tring Museum another undescribed 

 Goshawk, a young female shot by John Waterstradt on 

 Halmahera in September 1902. The colour of the upper- 

 side is brownish-black, each feather margined with rufous, 

 these margins being wider on the head and neck, so that 

 these parts look much more rufous. The underside is 

 bright tawny-ochraceous, each feather with a black shaft- 

 stripe. Wing-quills barred as in A. eudiabolus. Tail black, 

 with whitish-buff tip and fine brownish-grey bars. Wing 

 299 mm,, tail 225. There is no known species to which 

 this bird could be referred, but we think it is better to await
