the Lower Yangtse Basin. 495 



until the middle of April, but the northward movement begins 

 early in March. 



245. Anser cinereus, Meyer & WolflF. 



(703.) This is by no means one of the common Geese 

 with us. A good many are killed on Bush Island at the 

 mouth of the Yangtse, and I have seen specimens from 

 Chinkiang ; but on the upper reaches I have not identified it 

 for certain. 



The beak, legs, and feet are pale pink. 



246. Anser segetum (Gm.). 



(702.) Anser segetum, var. serrirostris, Swinhoe, P. Z. S. 

 1871, p. 417. 



The commonest Goose at the mouth of the Yangtse, and 

 (except A. erythropus) on the upper reaches too. The size 

 and. shape of the beak vary much, and I do not think species 

 can be founded on it. 



247. Anser cygnoides (L.). 



(706.) Found at the mouth of the Yangtse, but not 

 common. 



(Note. — I am under the impression that a Snow Goose — 

 probably A. hyperboreus, Pall. — visits the mouth of the 

 Yangtse, but I have been unable to obtain a specimen.) 



248. Nettapus coromandelianus (Gm.). 



(718.) Appears in considerable numbers in May; early 

 in June the young are flying about. They then frequent 

 the roofs of houses in the settlement, and particularly the 

 chimneys, where the parents and a brood of young may 

 often be seen together. They are said to nest in the 

 chimneys ; they also nest in hollow trees, and I have some 

 young in down taken on lOtli August, which must have 

 been a second brood. When not resting on the housetops, 

 they may be found among the rushes on the lakes. 



249. Dendrocygna javanica (Horsf.). 



The only specimen I have met with was obtained in 

 summer in Soochow, and is now in the Shanghai Museum 

 (Ibis, 1889, p. 446) .
