194 WILD FOWL OF INDIA. 



Bill and feet dull red. Length 23 inches ; extent 35 ; wing 10 J; 

 bill at front If. 



The Merganser is chiefly found, in India, on rivers within the 

 Himalayas, in small parties. I have frequently seen it on the great 

 Rungeet in Sikkim, and also in rivers in Kumaon, and on the 

 Ganges at Hurdwar. One instance only is recorded of its occur- 

 rence in Central India, it having been procured by Tickell at 

 Chybassa. Captain Smyth recently gave me two very large con- 

 cretions found in one of these birds, but I have not yet had them 

 examined. It is said to breed on holes of trees. 



The next species, from its small size, and shorter bill, as well 

 distinct mode of colouration, is separated as Mergellus. 



Gen. Mergellus. 



Char. — Bill shorter, and somewhat wider than in Mergus, the
