248 ANSERES. 



243. ANAS GALERICULATA. 



(MANDARIN DUCK.) 

 Anas ffaleri(ndata,JArme\iS, Syst. Nat. i. p. 539 (1766). 



The Mandarin Duck may always be recognized by the silver-grey 

 on the outer webs of its primaries. 



Kgures : Gould, Birds of Asia, vii. pi. 69. 



The Mandarin Duck is probably only a summer visitor to Yezzo, 

 but a resident in the more southerly Japanese Islands, where it is 

 very common on the small streams (Blakiston and Pryer, Ibis, 1878, 

 p. 213). It frequents the large lakes near Hakodadi (Whitely, Ibis, 

 1867, p. 207) . There is an example in the Swinhoe collection from 

 Hakodadi, obtained by Captain Blakiston in September ; and there 

 are eight examples in the Pryer collection from Yokohama. 

 Mr. Ringer has sent examples to the Norwich Museum obtained at 

 Nagasaki, where those procured by the Siebold Expedition were 

 doubtless also obtained (Temminck and Schlegel, Fauna Japonica, 

 Aves, pi. 127). In autumn it frequents the lakes in the interior in 

 large flocks, and feeds on the paddy-fields in company with the 

 Teal (Jouy, Proc. United States Nat. Mus. 1883, p. 318). 



The Mandarin Duck is a summer visitor to the valley of the Amoor, 

 but in Central and Southern China it is a resident. 



243. FULIGULA AMERICANA. 



(AMERICAN BLACK SCOTER.) 



Oidemia americana, Swainson and Bichardson, Faun. Bor.-Amer. ii. p. 450 

 (1831). 



The Black Scoter has dark axillaries and no white on the wing. 

 It has a large bill (width in front of the nostrils about 1 inch) . 



Figures : Baird, Brewer, and Ridgway, Water-Birds N. Amer. ii. 

 pp. 89, 90, 91 (woodcut and coloured woodcuts of head). 



The Diving Ducks form a very natural group possessing two 

 characters, either of which will distinguish them from the genus 

 Anas or from the genus Tadorna : the hind toe is furnished with a 

 well-developed lobe ; and the nostrils are placed very far forward. 

 The distance from the gape to the front of the nostril is more than 

 that from the tip of the bill to the front of the nostril.
