The birds of North and Middle America : a descriptive catalogue of the higher groups, genera, species, and subspecies of birds known to occur in North America, from the Arctic lands to the Isthmus of Panama, the West Indies and other islands of the Caribbean sea, and the Galapagos Archipelago . Birds. 134 BULLETIN 5 0, UNITED STATES NATIONAL MUSEUM exceeding distal secondaries by about one-third the length of wing, but extending little beyond tips of elongated proximal secondaries. Tail about half as long as wing, much rounded or slightly graduated, the middle rectrices tapering distally and subacuminate at tips, pro- jecting considerably beyond upper and slightly beyond lower coverts. Tarsus a little shorter than middle toe without claw, the acrotarsium with a single row of broad, transverse scutella, the planta tarsi with a single row of similar scutella on each side, the two of opposite sides in alternating or interdigitating contact along or inside of the rounded posterior ridge; outer toe with claw reaching about to base of middle claw, or falling very slightly short, the inner toe, without claw, reach- ing to or very slightly beyond penultimate articulation of middle toe;. Figure 9.—Porzana Carolina. Natural size. hallux, without claw, about as long as basal phalanx of outer toe; claws moderate in size, distinctly curved, acute, compressed. Plumage and coloration.—Plumage rather full and firm, that on head, neck, and anterior underparts blended; primaries firm and rather rigid, the rectrices much softer. Upper parts blackish, olive, or olive-brown, the back and scapulars spotted or striped with black and streaked with white; flanks broadly barred with white and dusky brownish gray or grayish olive, the axillars and under wing coverts also barred with white; under tail coverts (at least the longer ones) plain buff or buffy white.
