c. Tail not longer than combined length of tarsus and middle toe with claw.
d. Orbital region wholly feathered; outstretched feet reaching much beyond tip of tail; coloration varied.
e. Conspicuously crested and bearded; nostrils less widely separated (distance between them less than that from either to maxillary tomia); back and wings unicolored
Pithys (extralimital).[1]
ee. Neither crested nor bearded; nostrils more widely separated (distance between them greater than that from either to maxillary tomia); wings spotted or barred.
f. Bill relatively shorter (exposed culmen not more than one-fourth as long as wing) and broader (width at frontal antiæ much greater than its width at same point and equal to at least half the distance from nostril to tip of maxilla); back spotted or barred, or with a concealed patch of white; tail tipped with white or cinnamon
Hylophylax (p. 126).
ff. Bill relatively longer (exposed culmen more than one-fourth as long as wing) and more compressed (width at frontal antiæ very little if any greater than depth at same point and equal to less than half the distance from nostril to tip of maxilla); back neither spotted nor barred, nor with concealed white patch; tail unicolored.
Sclateria (extralimital).[2]
dd. Orbital region partly nude; outstretched feet reaching to but little if any beyond tip of tail; coloration plain
Anoplops (p. 130).
cc. Tail decidedly longer than combined length of tarsus and middle toe with claw.
d. Tail about two-thirds as long as wing; loral and frontal feathers dense; malar region wholly feathered; nostril narrow, longitudinal; culmen less sharply or not at all ridged; under parts unicolored.
e. Pileum crested; upper eyelid not feathered; culmen more contracted, slightly ridged; back and wing-coverts unicolored.

  1. Manikup Desmarest, Hist. Nat. des Tangaras, 1805, text to pl. 66. Type, Le Manikup de Cayenne Daubenton = Pipra albifrons Gmelin. — Pithys Vieillot, Nouv. Dict. d'Hist. Nat., xxiv, 1818, 112 (diagnosis but no type); xxvi, 1818, 520. Type, P. leucops Vieillot = Pipra albifrons Gmelin. — Dasyptilops Cabanis and Heine, Mus. Hein., ii, 1859, 8. Type, Pipra albifrons Gmelin. (Colombia to Guiana, Peru, and central Brazil; two or three species.) Notwithstanding its unquestioned priority, the name Manikup is so obviously both barbarous and cacophonous that it should not be employed as the generic term.
  2. Holocnemis (not of Schilling, 1829) Strickland, Ann. and Mag. Nat. Hist., xiii, 1844, 415. Type, H. flammulata Strickland = Sitta nævia Gmelin. — Heterocnemis (not of Albers, 1852) Sclater, Proc. Zool. Soc. Lond., 1855, 146 (new name for Holocnemis Strickland, preoccupied). Type, Sitta nævia Gmelin. — Sclateria Oberholser, Proc. Ac. Nat. Sci. Phila., June 2, 1899, 209 (new name for Heterocnemis Sclater, preoccupied). The above diagnosis must be taken with reservation as applying to this genus, as, unfortunately, no memorandum was made of the species upon which it was based. No species of Sclateria is represented in the U. S. National Museum collection.
  3. Rhegmatorhina Ridgway, Proc. U. S. Nat. Mus., x, sig. 33, Aug. 6, 1888, 525, footnote. Type, R. gymnops Ridgway. (Lower Amazon Valley; monotypic.)
