164 Mr. R. Swinhoe on Birds from Hakodadi. 
55. Yellow-nibbed Wild Duck. Anas zonorhyncha , 
'%% Swinh - 
A male specimen, just like the China bird. Blakiston 
writes, “ I have another, with broader bill, and more like a 
female Mallard. There is no doubt about the species ; but 
does it breed with the Mallard ?'' 
/£?£ 56. Falcated Teal. Eunetta falcata (Pall.). 
A male in full plumage. 
57. Common Cormorant. Phalacrocorax carbo (L.). 
An adult in spring plumage, and an immature bird; both 
without date and sex. 
58. Resplendent Shag. Phalacrocoraxpelagicus (Pall.). 
Phalacrocorax ceolus } Swinh. Ibis, 1867, p. 395. 
Two immature birds without date—one marked a female, the 
other unmarked. These specimens, which look very like the 
figure of the young Carbo bicristatus in the f Fauna Japonica 3 
(t. lxxxiv.B), I recognize, by their straight cylindrical bills and 
the proportions of their wing-quills, to belong to the allied 
form, my (Bolus , which Pallas long ago separated as G. pela- 
gicus (Zoogr. Rosso-Asiat. tom. ii. p. 303). In Chefoo I 
met with the species in breeding-plumage, and could then easily 
distinguish the birds by their bare face-skin being rubro- 
papillose, as Pallas describes it. But perhaps a more telling 
character is the proportions of the quills in the one species as 
compared with those in the other. P. pelagicus has the 2nd, 
3rd, and 4th primary quills equal and longest; while in P. 
bicristatus the 3rd alone is the longest. In P. bicristatus 
too, the face-skin is smooth and yellowish, and the bill is 
slightly inclined to turn up. P. tenuirostris , Temm., from 
Japan, given in Mr. G. R. Gray's f Hand-List/ is probably 
synonymous with Pallas's P. pelagicus , which, strangely 
enough, Mr. G. R. Gray identifies with the better-known 
P. bicristatus , Pallas.

59. Black-tailed Gull. Larus crassirostris , Vieill. 
An adult without sex or date marked. Mr. Howard Saun¬ 
ders, who makes a special study of this group, has examined
