and compared these Gulls from Japan, and confirms me in 
my identification of them. 
60. Larger Common Gull. Larus niveus , Pall. /$p 
An adult female without date. Mr. Saunders thinks that 
this is only a larger race of the Common Gull, L. canus. 
61. Great Black-backed Gull. Larus marinus , L. 
A fine male without date. This species is not mentioned in 
any of the Russian works that I have access to as occurring 
in these seas; nor do the Americans know it from the Pacific 
side of their continent. Pallas notes that he never received 
the species from Siberia. He further states that its hill is as 
in L. cachinnans, and he wonders whether they are really dis¬ 
tinct. This, I should think, would imply that the name L. 
cachinnans is referable to the large Herring-Gull of these seas, 
which we at present call either L. occidentalis, And., or L. 
borealis , Brandt, and not to the smaller bird like L. argen- 
tatuSy but with a darker back, which Schlegel unites with 
that species. 
62. The Burgomaster. Larus glaucus , L. 
An adult female shot in March. 
63. Large Grey-winged Gull. Larusglaucescens, Brandt. 
An adult male and a male in change from the immature. 
Both without date.

64. Laughing Hooded Gull. Chroicocephalus ridibun- 
dus (L.). 
There are three specimens of this :—a female shot in May, 
with a well-developed hood; a male shot in April, without 
hood; and a female shot 20th April, with many immature 
markings still showing on the upper plumage.

65. Flesh-billed Black Albatross. Diomedea derogata, 
Swinh. P.Z.S. 1873, p. 786. 
A bird of this species marked male, and dated July. A few 
of this species occurred at Chefoo, North China, in June. All 
1 procured were also males; and I described the bird in the 
P. Z. S. of last December. In the figure of this species in the
