Mr. R. Swinhoe on the Ornithology of Northern China . 89 
(2.) The Hobby. Falco subbuteo , L. 
(3.) Accipiter soloensis, Horsfield. 
(4.) Accipiter gularis, Schleg. Faun. Japon. ? 
Larger than the last, with longer bill, but without the streaks 
on the throat. The British Museum has one of this species 
from Shanghai. This must, for the present, be doubtfully referred 
to the Japanese bird. 
10. Tawny Owl. Otus brachyotus, L. ? 
Erase the note of interrogation. 
To the Owls I can now add 
(1.) Otus vulgaris, Fleming. 
(2.) Scops japonicus, Schleg. Faun. Japon. 
Probably identical with S. bakkamcena, Pennant, of India. 
(3.) Ninox japonica, Temm. Faun. Japon. 
Mr. Gurney considers the single specimen of this to be rather 
referable to the Japanese than to the Indian and Malasian N. 
scutulatus, Raffles. 
13. Swallow. Hirundo rustica , L. 
The oldest name for this form of the Common Swallow appears 
to be H. panayana, Gmelin, and not H. javanica, Sparrrn. 
14. Tiger-Swallow. Hirundo daurica. 
Should be H. daurica , Linn., nec Pallas. The synonym applied 
by the latter is H. alpestris. 
15. Sand-Martin. Cotyle rip aria? 
Is undoubtedly the C. sinensis of J. E. Gray. It is smaller 
than, and quite distinct from, C. riparia. I have lately procured 
this species at Amoy. 
To these three Swallows we can now add a fourth ; for Mr. 
Fleming’s series contains a mature specimen of a House-Martin 
(Chelidon ), hut unfortunately with its wings clipped. I exhibited 
this bird, with the rest of the North-China skins lent me by Mr. 
Whiteley, before the Zoological Society, on the 25th of November; 
and I will consequently extract from the paper then read my re¬ 
marks on the differentiation of this species from its fellows of the
