SCOLOPACID^: SANDPIPERS. 817 



mary decidedly longest ; inner secondaries moderately long and rather slender. Tail moderate, 

 slightly hilt decidedly doubly emarginate, central feathers projecting. Tarsus rather longer 

 than middle toe; tibia bare for half the length of tarsus; toes all long, slender, and slightly 

 margined. Adult in spring: Upper parts a nearly uniform light grayish-ash, each feather 

 with a central brownish-black field, deepening into pure black on scapulars, where also the 

 edgings of some feathers have a reddish tinge. Long inner secondaries sooty-brown, fading 

 into light ashy on the edges. Secondaries and greater coverts dark grayish-ash, edged and 

 broadly tipped with white. Primaries deep dusky, almost black on outer vanes and at tips, 

 the innermost edged with white ; shafts of all brown at base and black at tip, the central por- 

 tion white. Upper tail-coverts white, with sagittate spots of dusky. Tail-feathers ashy-brown, 

 the central pair darkest. Under parts white; jugulum, breast, and sides of neck with a slight 

 reddish tinge, and, together with sides, with numerous streaks and oval spots of dusky, which 

 become large and V-shaped on flanks. Length 9.50; wing 5.7.5; tail 2.75; bill L25; tarsus 

 1.12. Long Island, May 24, 1883; only one specimen known, still extant in U. S. Xat. Mus. 

 It is still uncertain whether this be a good species or an unusual state of T. canutus or A. ma- 

 cula ta ; A. 0. U. removes it to the Hypothetical List, No. II. 



A. acumiiia'ta. (Lat. acwmmata, acuminate.) Sharp-tailed Sandpiper. A large species, 

 of the size and with somewhat the general aspect of the Pectoral Sandpiper. Tail graduated, 

 almost cuueate, all the feathers more or less acuminate, the projecting middle pair particularly 

 so. Bill about as hmg as head ; tarsus equal to middle toe and claw; toes perfectly free. Crown 

 bright chestnut, streaked with black, bounded by decided whitish superciliary lines; diflferent 

 from hind neck. Upper parts with pattern of coloration of those of maculata, the feathers being 

 black, with bright chestnut edges, and many of them also with whitish tips, the edgings not 

 making scallops, and particularly straiglit and firm on the long inner secondaries. Central 

 field of rump and upper tail-coverts black, scarcely or not varied with reddish tips of the feath- 

 ers, the sides of this ai'ea white with dusky touches. Tail-feathers dusky, the middle ones 

 darker or black, all firmly rimmed about with chestnut, butf, or whitish edging. Primaries 

 blackish, their shafts mostly white; secondaries dusky, successively acquiring white tips and 

 edges; greater coverts dusky, white-tipped. Entire under parts white, more or less suffused 

 on jugulum, breast, and sides with a light ruddy brovA'n (much as in Podasocys nwntanus), 

 the jugulum alone with a set of small sharp dusky touches, being an extension across throat 

 of better pronounced streaks of sides of head, neck, and brea.st, leaving chin definitely pure 

 white. The effect is quite different from that produced by the heavy streaking of maadata. 

 Bill changing from greenish-yellow basally to blackish toward tip; feet greenish-yellow. 

 Length 8.00-9.00 ; winsr 5.2.5-5.. 50; tail 2.25-2.50; bill 1.00; tarsus 1. 10-1.20; middle tue and 

 claw the same. (Described from several late summer and early fall specimens, taken in Alaska. 

 An Australian specimen before me is smaller (wing under 5.00, etc.), and, excepting crown, 

 lacks any reddish of upper parts, all the edgings being simply gray ; ruddy sufi'usiou of breast is 

 scarcely seen.) An interesting species, widely diff'used in the Old World, found in summer in 

 Alaska, where it is common in some localities, as Saint Michael's, and where it doubtless breeds; 

 extent of migration in America, if any, unknown. Figured in Nelson's Alaska, 1887, pi. 7. 

 ARQUATKL'LA. (Lat. anjitatrUa, dim. of arquata, for arcuata, bowed.) FEATilER-I.Ea 

 Sandi'ipku.s. Kock Sandpipers. Bill, tarsus, and middle toe obviously not of ot\ni\\ 

 lenirths. Tarsus shorter than bill or middle toe and claw ; tibial feathers reaching suffnigo. 

 Toes very louir. broadly margined, and flattened underneath. Hind toe very short; claws 

 short and blunt. Tail moderate, wedge-shaped. Bill variable, always longer than head, 

 straight or slightly decurved, very slender, much compressed, tip scarcely expanded, irroove 

 on lower mandible shallow or olisolete. A generic group established by Baird, 18.58. upon 

 the well-known "Purple" Sandpiper, to which two other species have been added: reduced 

 to a subgenus of Tiinria by the .\. 0. U. The f<dlowini: analysis is taken from Bull. Nutt.
