Gruidae. 



(Grrus sp.? 



A gray crane, of some species, that Mr. Koren thought was 

 GriLS canadensis (Linn.), was seen at the following places: forty 

 miles east of Cape Bolshaja Baranov, July 18, 1912; Balagan, 

 July 19, and on the mainland side of Sebddij Sound. They were 

 always exceedingly shy, and Mr. Koren never succeeded in getting 

 a shot at one. 



The Eastern white stork (Ciconia hoyciana Swinh.) was reported 

 by the natives to breed regularly in upper Kolyma as far north 

 as Sredna Kolymsk, and occasionally to straggle even to Nijni 

 Kolymsk. None were observed by Mr. Koren. 



Anatidae. 



Mergus serrator Linn. 



The red-breasted merganser was common in the early summer 

 in the Kolyma River, but never was observed anywhere on the 

 coast. 



Mareca penelope (Linn.). 



The widgeon arrived at Nijni Kolymsk on June 5, 1912, and 

 soon became common in the Kolyma River region, only, how- 

 ever, within the limits of tree growth, never being seen in open 

 tundra. 



Nettion crecca (Linn.). 



Teal arrived at Nijni Kolymsk with widgeon on June 5, and soon 

 afterwards became common within the tree growth, beyond which 

 they never were seen. 



An adult male was taken at Nijni Kolymsk, June 7, 1912.
