72 SCHINZ’S SANDPIPER. 
marginal tip on the inner web; the two middle surpass the others 
by a quarter of an inch, are somewhat pointed, and entirely 
blackish. The feet are blackish; the naked space above the heel 
half an inch ; the tarsus seven eighths of an inch long, and much 
longer than the middle toe, the toes are cleft to the base; the 
nails are blackish. As will easily be perceived the specimen 
described is in the winter dress. 
This Sandpiper is well known to appear in a summer vesture 
analogous to that of Tringa alpina at the same season; but we 
have never met with an American specimen in that state. 
In the full-plum aged males the bill and feet are black: irides 
brown : before the eye a small blackish patch surmounted by a 
white stripe dotted with blackish gray. Head above, back and 
wing-coverts bright rufous, the feathers with merely a black cen¬ 
tre : colors not so bright as in Tringa alpina: wings above blackish 
gray with black shafts; point of the primaries black, with white 
shafts : the ten middle tail-feathers as well as their upper coverts 
are blackish: the lateral cinereous with their coverts white: the chin 
is white, the sides of the head and hind neck are of a ferruginous 
gray : throat white, longitudinally spotted with rufous gray; the 
breast almost entirely of a jet-black color, always interrupted by 
some insulated white feathers, and never so broadly black as in 
Tringa alpina: all the remaining under parts are white, with a very 
few dusky streaks on the sides. 
At one year of age the male is on the back of a less bright 
rufous spotted with black: on the breast the black consists 
merely of a spot, and is mixed with many white feathers. The 
female much resembles the male at the same age. The very 
young is above of a ferruginous color varied with white, yellowish, 
and black; all beneath white, streaked with dusky ferruginous on 
the throat.
