39. DAFILA ACUTA ACUTA (Linnaeus). 



One male, 7 miles north of Nijni Kolymsk, May 25, 1915. 



40. CLANGULA CLANGULA CLANGULA (Linnaeus). 



One specimen, Annuj River, October 4, 1914. 



41. HARELDA HYEMALIS (Linnaeus). 



Four males. Cape Bolshaja Baranov, July 22 and 23, 1915; one 

 female, Kolyma Delta, July 14, 1915. 



Three of the males have lost the long central tail feathers, and 

 the remainder of the tail is much worn, and in all four the scapulars 

 are mostly molted, and the fulvous of the upper back is much faded 

 and worn. 



We saw this back in September (1914) on the Lesser Annuj River. This year 

 (1915) we saw great quantities of them at the delta of the Kolyma and along 

 the Chorchee coast. They were by far the commonest duck observed. — C. A.
