152 SOME CHINESE VERTEBRATES. 



Many of the Anatidae taken by Mr. Zappey are more or less colored a 

 rusty red on the underparts; this is due to some extraneous stain obtained from 

 the water and while all the specimens taken near Ichang are comparatively 

 free from discoloration all those taken in small streams and ponds at higher alti- 

 tudes are similarly discolored. 



NETTA RUFINA (Pallas). 



One very fine adult male in full plumage, Kiating, western Szechwan, 

 November 22, 1908. 



MARILA FERINA (Linne'). 

 One adult male, Kiating, western Szechwan, November 22, 1908. 



MARILA FULIGULA (Linn6). 



Four males, none in full adult plumage, Ichang, Hupeh, and Kiating, west- 

 ern Szechwan, November. 



CLANGULA CLANGULA CLANGULA (Linn6). 

 One adult male, Yachow, western Szechwan, December 5, 1908. 



MERGELLUS ALBELLUS (Linne"). 







Two specimens, male and female, the male in eclipse plumage similar to 

 that of the female, Ichang, Hupeh, November, and December. 



MERGUS MERGANSER MERGANSER Linne". 



Four specimens, adults of both sexes, Ichang, Hupeh, and Kiating, Szechwan, 

 December, and January. 



It is of course problematical where these birds were bred and they perhaps 

 should all be referred to M. m. comatus, rather than to M. m. merganser, all 

 being smaller than European specimens. In the slight color differences, and 

 the character of the crest of the male, they are more or less intermediate though 

 on the whole nearer to true M. m. merganser. 



MERGUS MERGANSER COMATUS (Salvadori). 



Two specimens, male and female adult, Kungyahsien, western Szechwan, 

 December 6, 1908.
