54 BREWSTER AND BANGS—A NEW BECARD eo 
Characters.— Nearest to P. polychropterus of Brazil, but larger and darker; 
rump and upper tail coverts sooty blackish, the feathers only slightly edged 
with dark gray; white edgings of wings much narrower; white spots (or 
patches) at sides of scapulars almost absent —just indicated by a white line 
or two; under parts darker, more sooty; under wing coverts and lining of 
wing darker gray; bill somewhat narrower and deeper. 
Color.— Type, adult ¢ (2 unknown): Pileum shining blue-black with a 
slightly scaly appearance; back black, and sides of head and neck nearly so; 
lower rump and upper tail coverts blackish, with dark gray edges to the 
feathers; two or three of the outermost scapulars with white outer edges; 
wings dark hair-brown with narrow white outer edges to the greater coverts, 
only the middle coverts being broadly edged with white; outer margins of 
secondaries narrowly edged with whitish, the inner margins with more or less 
yellowish white, especially near the bases of the feathers; under parts dark 
sooty gray, paler on belly and under tail coverts, where the feathers are also 
slightly tipped and varied with light grayish or grayish white; under wing 
coverts gray, slightly varied and streaked with whitish; rectrices brownish 
black, tipped with white —to a depth of Io mm. on the outermost feathers, 
and scarcely perceptibly on the central pair; bill (in dried specimen) bluish 
black, tip of mandible and a spot in middle of culmen bluish white; foot and 
tarsus blackish. 
No. 31,131, @, has the appearance of being younger than the type, and 
differs in having the rump and upper tail coverts more decidedly gray, with 
an olivaceous tinge, and in being paler gray below, the feathers more noticeably 
varied with light gray. It also has the inner web of the curious aborted second 
primary (characteristic of the males of this genus) pure white, except for a 
narrow space near the tip, whereas in the type this feather, like the other 
primaries, is of a nearly uniform dark hair-brown. 
Measurements.— Type, @ adult: wing, 83.5; tail, 65.; tarsus, 19.; exposed 
culmen, 12.6 mm. 
Topotype, no. 31,131, @: wing, 84.; tail, 64.; tarsus, 19.6; exposed
