Genus PH^EN ICOPHILUS Strickland. 



Plurnicophilus Strickland, Jardine's Contr. Orn., 1851, 104. (Type, T^mlus 

 palmarum Linnseus.) 



Medium sized, plainly colored Tanagers with the bill rather small 

 and slender (exposed cidmen, however, at least two-thirds as long as 

 tarsus), tail even, shorter than length of wing to tips of secondaries, 

 and outermost (ninth) primary longer than third; adults olive-grcen 

 above, gray or gray and white beneath, the head chiefly black. 



Bill' nearly as long as head, slender-conoid, its depth at base much 

 less than half the length of exposed culmen, and about equal to or 

 slightly greater than its basal width; exposed culmen about four-fifths 

 as long as tarsus, nearlv straight for about the basal half, then grad- 

 ually decurved to the slightly uncinate tip; gonys a little shorter than 

 distance from nostril to tip of maxilla, nearly straight; maxillary 

 tomium gentlv concave throughout, distinctly notched subterimnally; 

 mandibular tomium faintlv convex terminally, then straight to the 

 decided but not abrupt l)asal deflection. Nostril wholly exposed, 

 nearly circular, in anterior end of nasal fossae, bordered behind by 

 membrane. Rictal bristles short, indistinct. Wing moderate (about 

 three and a half to three and three-fourths times as long as the rather 

 long tarsus), rounded (seventh and sixth primaries longest, ninth 

 shorter than fifth); primaries exceeding secondaries by less than length 

 of maxilla from nostril. Tail shorter than wing by considerably less 

 than length of tarsus, even or very slightly rounded, the rectrices 

 rather narrow, with firm webs and rounded tips. Tarsus decidedly 

 longer than middle toe with claw; outer claw reaching to base of mid- 

 dle claw, the inner claw not quite so far; hind claw shorter than its 

 (jigit— all the claws well curved and sharp.
