496 Mr. F. W. Styan on the Birds of 



250. Tadorna vulpanser, Flem. 



(712.) T. cornuta (Gra.), Swinhoe, P. Z. S. 1871, p. 418. 

 A coast bird, found near Shanghai in winter, but not met 

 with higher up the Yangtse, 



251. Casarca rutila (L.). 



(713.) An inland bird, common in winter on the river and 

 adjacent waters. Almost always found in pairs, though a 

 dozen or more pairs may be together. 



252. Aix galericulata (L.). 



(719.) A local bird. Fairly common round Kahing. 

 Scarce at Kiukiang, where I have only obtained a single 

 specimen. 



253. MaRECA PENELOPE (L.) . 



(715.) Abundant. 



254. Dafila acuta (L.). 

 (714.) Abundant. 



255. Anas boschas, L. 



(710.) Abundant. Appears at the end of September, and 

 remains till early in April. 



256. Anas zonorhyncha, Swinhoe. 



(711.) Our only resident Duck. I have taken eggs in 

 May, and also in July, probably a second brood. The 

 breeding-plumage is more rufous than winter dress, espe- 

 cially on the crown of the head, 



257. Chaulelasmus streperus (L.). 

 (716.) Not common. 



258. Querquedula crecca (L.). 



(721.) Very abundant. The earliest arrival noted is 12th 

 September, and some flocks still remain in the first week 

 in May. 



259. QUERQUEDULA CIRCIA (L.). 



(720.) This is evidently a more southern bird. In winter 

 I have never seen it, but in April it is rather abundant, 

 mingling with flocks of Common Teal.
