Mr. H. KiRKE SwANN exhibited a new Goshawk from 

 Japan on behalf of Dr. Hartert and himself, and made the 

 followino- remarks : — 



When Dr. Hartert and I were examining the Palrearctic 

 Goshawks at Tring a few weeks ago for his paper in the 

 forthcoming number of ' The Ibis/ we noticed two skins 

 from Japan which did not agree with any known race, 

 and considered it necessary to lay them aside for further 

 examination. No adult bird from Japan exists in the 

 British Museum collection, but, after examining the four 

 immature birds there, we feel that the Japanese bird is 

 distinct and has hitherto been overlooked or confused with 

 A. g. schvedowi, owing to the lack of adult skins. We 

 therefore propose to call it 



Astur gentilis fujiyamae, subsp. nov. 

 Type. In the Tring Museum. Ad. S ? Sagami-no-kuni, 

 Japan. A. Owston coll. 



This is the smallest known form of Astur gentilis, and 

 differs from A. g. gentilis in being very much smaller 

 and blacker above ; from A. g. schvedowi in being appre- 

 ciably smaller and very much darker, more blackish above, 

 and rather more heavily barred below. It most resembles 

 in size and dark coloration A. g. arrigonii of Sardinia.

Dr. P. H. Manson-Bahr exhibited on behalf Mr. E. 

 Huntley, of Crockham Hill, Kent, an abnormal Whitethroat * 

 * Editors Note : — A very interesting paper by Mr. J. P. Burkitt, in 

 which attention was called to the singing of mateless Whitethroats 

 and to their building of a series of cock-nests, appeared in ' The Irish 

 Naturalist; vol. xxx. (1921).
