"^^"4^] THAYER AND BANGS — BIRDS 23 



Unfortunately we have before us but one fully adult bird in 

 breeding plumage from western Europe, no. 36,625, M. C. Z., 

 from England. This specimen is of about the same size as the 

 Siberian examples, measuring: wing, 197; tail, 69; tarsus, 45; 

 exposed culmen, 30 mm. It is, however, darker in the color of the 

 upper parts. ^Yhether or not there are two races in Euro-Asia, — 

 which we have no means of proving or disproving now, and there- 

 fore we accept Mathews's opinion, — the American bird is certainly 

 very small in comparison, and should, we think, receive a name. 

 In eighteen fully adult American birds in breeding plumage, the 

 wing ranges from 175 in the smallest, to 193 in the largest, with 

 the average 187.1 mm. We also have measured numerous young 

 American birds in gray plumage, and have compared the results 

 with measurements of gray birds from Malayan regions, and have 

 found the same differences in size. The small American bird we 

 propose to call Squatarola squatarola cynosurce subsp. nov. Type 

 from Baillie Island, Arctic America, no. 2,657, Bangs coll., M. C. Z., 

 adult male in full breeding plumage, collected July 13, 1901. 

 It measures: wing, 183; tail, 65; tarsus, 45; exposed culmen, 

 28 mm. 



Pluvialis dominicus fulvus (Gmelin). 



Eight specimens, adults of both sexes and young in autumn 

 plumage, besides downy young and many sets of eggs, from Nijni 

 Kolymsk, Cape Bolshaja Baranov, Chelakhskai Point, and Chaun 

 Bay, May 30 to Aug. 27, 1912. The first golden plover to arrive 

 at Nijni Kolymsk was on May 30. At Troyan Bay at the mouth 

 of the Kolyma, on June 30, two sets of four eggs each were found. 

 At Cape Bolshaja Baranov, July 5, two sets were taken, also of 

 four eggs each; these were near hatching. The species bred com- 

 monly along the whole Arctic coast of Siberia, but always nested 

 in hilly tundra, where the ground was sprinkled with a whitish 

 moss. 



Mr. Koren watched the habits of the birds closely, and found 

 that the males appear to do all the incubating in the early stages,
