 when the eggs are nearly ready to hatch, she appears again and takes 

 her turn with the male. When the young are hatched, both 

 parent birds are always with them. 



At Cape Chelakhskai, Aug. 27, 1912, large flocks of young birds 

 were seen, ready to migrate. 



Eudromias morinellus (Linn.). 



Two adults, male and female, taken at Nijni Kolymsk, June 4,

 the East, and become established there as a breeding species. 



Charadrius hiaticula Linn. 



One adult female was taken at Nijni Kolymsk, May 31, 1912. 

 The ringed plover was first seen. May 31. Afterwards it often was

 nor young birds were found. 



Morinella interpres oahuensis (Bloxham). 



The Eastern turnstone was seen July 19, at Balagan, where 

 several pairs were breeding, associated with black-bellied plovers, 

 on the dry, mossy spits. Again at Ajan Island, July 23, the 

 species was found, also sharing the breeding grounds with black- 

 bellied plovers. No specimens were taken. 



Morinella melanocephala (Vigors). 



A flock of about twenty black turnstones was seen at Chaun Bay, 

 Aug. 15, 1912, which was the only time the species was observed 

 in Siberia during the trip.
