Adult in spring. — Upper parts grayish-brown and many feathers have black cen- 
ters with paler edges; rump and upper tail-coverts chiefly white with irregular bars 
or spots of black or biownish ; streak over eye, chin, throat and breast rusty-red ; 
belly, flanks and under tail-coverts white or nearly white ; sides whitish with dusky

autumn, have upper parts more grayish and less black, and lower parts generally 
white. 
Habitat. — Nearly cosmopolitan ; breeds in high northern latitudes, but visits the 
Southern Hemisphere during migrations. 
The Eiobin-snipe or Gray -back, as the Knot is called by hunters on 
the Atlantic coast of New Jersey, where it is abundant during- mig-ra- 
tions, is a reg-ular and somewhat common visitor about the lake shore 
and at Erie bay, in Erie county, during- the spring- and fall migrations. 
In other parts of the state the Knot is seldom seen. 
Tringa maritima Brunn.

Habitat. — Northern portions of Northern Hemisphere , in North America chiefly 
the northeastern portions, breeding in the high north, migrating in winter to the 
eastern and middle states, the great lakes and the shores of the larger streams in 
the Mississippi valley. 
This species I have never met with in Pennsylvania, where it occurs 
only as a very rare or casual mig-rant. Mr. George B. Sennett, of Erie 
city, mentions it as a straggler in his locality. The late Judge Libhart 
records in his report the capture of a Purple Sandpiper in August (year 
not given) in Lancaster county. A specimen in the U. S. National 
Museum was taken many years ago near Philadelphia.
