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 Perry’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 gularis , 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. 13 , Lusciniopsis japonica. This is undoubtedly the Locus- 
tella ochotensis , Middendorff, ‘ 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
