Genus PIPRITES Cabanis. 



Piprites Cabanis, Weigman's Archiv., xiii, pt. i, 1847, 234. (.Type, Pipra pileata 



Temminck.) 

 Hemipipo Cabanis, Weignuin's Archiv., xiii, pt. i, 1847, 234. (Type, Pipra 



chJoris Cabanis.) 



Medium-sized Pipridse (wing about 62-75 mm.) having the second 

 phalanx of middle toe wholly free from outer toe. 



Bill small,'' less than half as long as head, its depth at nostrils 

 greater than its witlth at same point, and equal to much more than 

 half the distance from nostril to tip of maxilla ; culmen nearly straight 

 basally, then gradually and decidedly curved, the tip of maxilla dis- 

 tinctly uncinate; gonys longer than mandibular rami, slightly but 

 decidedh" convex; maxillary tomium straight or slightly concave, dis- 

 tinctly notched aubterminally. Nostril mostly covered by antrorse 

 and decumbent bristly nasal plumules, rather large, roundish or 

 broadly oval, with narrow superior membrane. Rictal bristles well 

 developed, and bristly tips of antrorse latero-frontal and mental 

 plumules equally large. Wing moderate, with longest primaries 

 exceeding secondaries by about length of tarsus to nearly as long as 

 the latter; eighth and seventh primaries longest, the ninth and sixth 



a I consider this to be probably the same as L. rufescens for the reason that every one 

 of the color characters ascribed to it applies perfectly to the adult of the latter, which, 

 apparently, was unknown to the describcr of .4. tcrlia. 



b In form and relative size the bill of this genus is remarkably similar to that of cer- 

 tain species of the genus Vireo ( V. huttoni, V. carmioli, etc.), and the coloration is also 

 decidedly "vireonine."
