Mr. R. Swinhoe on the Ornithology of Northern Japan. 443 



add a few remarks to the interesting papers already given on 

 this subject by Captain Blakiston (Ibis, 1862, p. 309, and 1863, 

 pp. 97-100). 



Captain Blakiston, in his first paper, refers to the article on 

 Japanese birds in Peri'y's 'Expedition to Japan' (vol. ii. pp. 219- 

 235), but he neglects to add to his Hakodadi list one bird in 

 particular which Mr. Cassin there notes as for the first time 

 observed in Yesso. This is the Accipiter yularis, Temm. The 

 occurrence of this small Hawk in the northernmost island is 

 interesting. With regard to such wandering creatures as Lobipes 

 hyperboreus, their discovery in Japan is nothing astonishing, as 

 we have already observed them periodically abundant on the 

 Chinese coast. 



Mr. Cassin's paper in the Philadelphian ' Proceedings ' is 

 entirely devoted to a collection of birds made at Hakodadi, con- 

 cerning which I have the following remarks to make. 



No. 4, Passer montaninus, Pall. ? The bill and feet of the Tree- 

 sparrow (so-called) of Hakodadi are noticed as much stronger 

 than those of French specimens. I have specimens from several 

 parts of China varying greatly in these peculiarities, even in birds 

 from the same locality, and therefore cannot regard them as other 

 than individual variations. 



No. 6, Alauda japonica. The Japanese Lark is doubtless a 

 Wood-Lark, and I think future observation will prove it to be a 

 tree-frequenting species. In form of bill and in many respects 

 it is very similar to the European Alauda arborea, L. 



No. 11, Anthus japonicus, T. & S. This is the first bird not 

 noticed by Captain Blakiston. 1 cannot help thinking that it 

 will turn out to be the winter plumage of Anthus cervinus, Pall., 

 which is a winter visitant to South China, and probably retires 

 to Japan and North China to breed. 



No. IS, Lusciniopsis japonica. This is undoubtedly the Locms- 

 tella ochotensis, Middendorfi", ' Sibirische Reise,' which von 

 Schrenck, in his ' Amurland,^ wrongly considers identical with 

 L. certhiola, Pall., a much larger bird. Of this species Captain 

 Blakiston also procured a specimen, and in his first paper referred 

 it by mistake to Calamoherpe cantillans. In his second paper, at 

 my suggestion, he corrected the mistake (Ibis, 1863, p. 98). His
