196 BULLETIN 50, UNITED STATES NATIONAL MUSEUM. 
Rather large, snipe-like Eroliine (?) (wing 135-150 mm.) with 
bill at least two-fifths (sometimes half) as long as wing, with the 
slightly expanded and punctulate terminal portion occupying one- 
third or more of its total length; tarsus less than twice as long as 
middle toe without claw, and without web at base of inner inter- 
digital space. 
Bill two-fifths to one-half as long as wing, straight, compressed 
for proximal two-thirds, the terminal third slightly but distinctly ex- 
panded, depressed, and minutely punctulate; culmen ascending ba- 
sally, the base of bill much higher than wide; nostril sub-basal, small, 
longitudinally elliptical or linear; nasal groove extending to near 
middle of expanded terminal portion of maxilla; latero-frontal antia 
forming a straight, sometimes oblique, vertical line from base of 
culmen to rictus, the malar antia sometimes a continuation of the 
same line but usually forming a more or less convex or obtuse 
angular projection, the mental antia more or less (never very much) 
anterior to the malar antia. Wing moderate, pointed, the longest 
primary (outermost) exceeding distal secondaries by about half the 
length of wing; tertials elongated, tapering distally but rounded at 
tips, the longest falling decidedly short of tip of longest primary. 
Tail between one-third and two-fifths as long as wing, very slightly 
rounded; rectrices, 12. Tarsus much shorter than exposed culmen, 
one-fourth as long as wing or very slightly less, transversely scutellate 
anteriorly and posteriorly, but scutella of planta tarsi much smaller 
than those of acrotarsium; bare portion of tibia decidedly shorter 
than middle toe without claw, with transverse scutella distinct only 
on lower portion, both before and behind; middle toe about three- 
fourths as long as tarsus, the outer and inner toes; successively, de- 
cidedly shorter; hallux small and slender, shorter than basal pha- 
lanx of middle toe; claws rather small, moderately curved, sharp; 
basal phalanges of outer and middle toe connected for about half 
the length of the former, the space between inner and middle toe 
entirely without web. 
Coloration.—Lower back, rump, upper tail-coverts, and tail white, 
the first often immaculate, the rump spotted, the upper tail-coverts 
and tail barred with blackish; axillars and under wing-coverts white 
with V-shaped bars of dusky; summer adults with under parts 
mostly dull light pinkish cinnamon, more or less spotted or barred 
with dusky, the back, scapulars, etc., variegated with black and pale 
cinnamomeous; winter plumage nearly plain brownish gray above, 
plain white and pale gray beneath. 
Range.—Northern North America, migrating to Middle and South 
America. (Monotypic.)
