164 Mr. R. Swinhoe on Birds from Hakodadi. 



55. Yellow-nibbed Wild Duck. Anas zonorhyncha, 

 Swiuh. 



A male specimen, just like the China bird. Blakistou 

 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. Phalacrocorax pelayicus (Pall.) . 

 Phalacrocorax aolus, 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 ' Fauna Japonica ' 

 (t. Ixxxiv. b), I recognize, by their straight cylindrical bills and 

 the proportions of their wing-quills, to belong to the allied 

 form, my (solus, 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. pdagicus has the 2iid, 

 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. tenuii'ostris, Temm., from 

 Japan, given in Mr. G. R. Gray^s ' Hand-List,^ is probably 

 synonymous with Pallas's P. pclayicus, which, strangely 

 enough, Mr. G. R. Gray identifies with the better-known 

 P. bicristatus, Pallas. 



59. Black- tailed Gull. Larus crassii'ostris, Vieill. 



An adult without sex or date marked. Mr. Howard Saun- 

 ders, who makes a special study of this group, has examined
