successively shorter, the tenth longer than fifth. Tail slightly shorter 

 than wing to end of secondaries, much rounded (its graduation equal 

 to or more tiian length of exposed cuhnen), the rectrices moderate in 

 width, with rounded tip. Tarsus longer than commissure, slender, its 

 scutellation typicalh" exaspidean, but with acrotarsal scutella some- 

 times fused, or nearly so, on outer side ; middle toe, with claw, shorter 

 than tarsus, its second phalanx wholly free from outer toe, its first 

 phalanx wholly united to inner toe; outer toe, without claw, reaching 

 to beyond middle of subterminal phalanx of middle toe, the inner toe 

 nearly as long; hallux, without claw, slightly shorter than inner, slen- 

 der, its basal pad (tylarus) neither expanded nor flattened. 



Plumage ami coloration. — Contour plumage soft and blended ; head 

 normally feathered ; coloration above olive-greenish, with or without 

 gray on head or neck; wings dusky with olive-green or yellowish edg- 

 ings, the tertials usually, and greater wing-coverts sometimes, with 

 large terminal spots of pale yellow or ^^ellowish white; beneath light 

 olive-greenish or yellowish or pale gray, becoming yellowish on upper 

 throat and under tail-coverts; sexes essentiallly alike in color.« 



Nidijication. — (Unknown ?) 



Range. — Costa Rica to Ecuador and southeastern Brazil. (Five 

 species.) 



PIPRITES GRISEICEPS Salvin. 

 GRAY-HEADED MANAKIN. 



Adult male. — Pileum, hindneck, and sides of head (including 

 loral, orbital, auricular, and malar regions) plain slate-gray, relieved 

 by a conspicuous and continuous orbital ring of white; back, scapu- 

 lars, rump, upper tail-coverts and lesser wing-coverts uniform bright 

 olive-green; tail didl black, tipped with pale buffy grayish brown, 

 the outer webs of rectrices edged with olive-green, or pale buffy olive, 

 this increasing in extent toward outermost rectrix, on which it occu- 

 pies, approximately, the terminal third, the basal portion ])eing 

 dusky grayish brown instead of blackish; wings (except lesser coverts) 

 dull black or dusky, the middle coverts broadly tipped or terminally 

 margined with olive-green, the outer webs of greater coverts mostly 

 olive-green (edged terminally with yellowish), the remiges edged 

 with olive-green, most broadly on secondaries, the innermost of which 

 has the outer web wholly olive-green, the inner web wholly pale yel- 



a The above characters are taken from the four species constituting the genus Hemi- 

 pipo of Cabanis. The type of Piprites {Pipra pileata Temminck) is very different in 

 coloration, the male being chestnut above with black pileum, wings dusky with green- 

 ish edgings, under parts fulvous, becoming yellowish on abdomen; the female is simi- 

 lar, except that the liack is olivaceous instead of chestnut. According to Sclater (Cat. 

 Birds Brit. Mus., xiv, 28.3) Piprites pileatus (which I have not seen) would appear to 

 present certain structural differences, and I would not be surprised to find that it is 

 generically separable from the group named Hemipipo liy ('at)anis.
