tail-ooverts white. Under parts white; with short longitudioal lines and spots of dark 

 brownish cinereous on the neck and breast; quills brownish black, with a large longitudi- 

 nal space of white on' their inner wobs and also on the outer webs of the shorter pri- 

 maries. Yoiino: Upper parts lighter, and with the white spots more irregular or scarcely 

 assuming a circular shape; naiTOW lines on the neck and breast more numerous. 



Total length about 11.50 inches; wing, 7.50; tail, 3.00: oulmen, about 1.10; tarsus, 1.95; 

 middle toe, 1.15. 



In general coloration this .species resembles very closely the 

 Golden Plover {Chaimh'lns (hiiumcm), but, be.sides being much 

 larger and stouter built, may always be distingui.shed by tiie 

 blackish axillars, these feathers being smoky gray in the Golden 

 Plover. 



This species, the largest of our Plovers, is more or less com- 

 mon during the migrations. In Cook county, according to Mr. 

 Nelson, it "arrives in full breeding plumage the last of May and 

 after lingering a few days the majority pass north. A few re- 

 main during the summer and undoubtedly breed. Returning 

 early in September in fall plumage, they remain until well into 

 October. While with us in the migrations this species is gen- 

 erally solitary, sometimes a half dozen individuals joining com- 

 pany, or a single specimen will be found leading a miscellaneous 

 company of sandpipes and small plovers." 



SuB(iENUs Charadrius Linn.eus. 



Gkaradriiis Linn. S. N. od. 1". 1758, 150; ed. 12, 1766. 253. Type, C. aiiricariits Linn. 



Chak. Similar to Saimtoro/a. but without any trace of hind toe. Plumage also very 

 similar, but form rather more slender. 



Only two species of Charadrius proper .are known; one peculiar to the Palii'arctic 

 Region, but occurring accidentally in Greenland: the other spread over the remaining 

 portions of the world, including the greater part of America, the islands throughout the 

 Pa<_'iflc. and the coasts of Asia. They differ chiefly in the color of the axillary feathers and 

 the lining of llie wings, which .ire white in ('. niirirariiis, smoky gray in V. dotninicus.
