- ee. Pileum not crested; upper eyelid feathered; culmen broadly rounded; back and wing-coverts conspicuously spotted.
Phlegopsis (extralimital).[1]
- dd. Tail nearly as long as wing; loral and frontal feathering scant; nostrils rounded; culmen more sharply ridged; malar region partly nude; under parts (as well as upper) conspicuously spotted
Phænostictus (p. 134).
aa. Planta tarsi broadly rounded behind, composed of a single row or series of scutella, the inner edge of which is more or less prominent and convolute, separated (at least in part) from the inner edge of the acrotarsium by a narrow groove. (Grallariinæ.)
- b. Tarsus shorter than commissure, shorter than middle toe with claw; feathering head very short, more scale-like; bill slender, with mesorhinium very broad and flattened basally. (Rhopoterpeæ)
Rhopoterpe (p. 138).
- bb. Tarsus much longer than commissure, much longer than middle toe with claw; feathering of head normal; bill stouter, the mesorhinium narrow and compressed (normal) basally.
- c. Exposed culmen more than one-fourth as long as wing; tip of maxilla more strongly uncinate; rictal bristles obsolete; postocular region nude. (Pittasomæ)
Pittasoma (p. 140).
- cc. Exposed culmen less than one-fourth as long as wing; tip of maxilla less strongly uncinate; rictal bristles obvious (sometimes very distinct); postocular region feathered. (Grallariæ.)
- d. Nasal fossæ short and broad (distance from their anterior end to base of exposed culmen equal to not more than half the distance from the former to tip of maxilla), more or less triangular, the nostrils more oblique and in contact with latero-frontal antisæ or separated from the latter by a very slight interval; rictal bristles obvious; bill stouter, triangular in lateral profile, relatively deeper at base; depth at frontal antiæ equal to three-fifths to two-thirds the distance from nostril to tip of maxilla, or else the nostrils partly concealed by latero-frontal feathers.
- e. Tarsus only about one-third as long as wing; middle toe, without claw, three-fifths as long as tarsus; bill much broader basally, its width at frontal antiæ equal to about three-fifths the distance from nostril to tip of maxilla; rictal bristles more than half as long as bill; very small (total length less than 100 mm.)
- d. Nasal fossæ short and broad (distance from their anterior end to base of exposed culmen equal to not more than half the distance from the former to tip of maxilla), more or less triangular, the nostrils more oblique and in contact with latero-frontal antisæ or separated from the latter by a very slight interval; rictal bristles obvious; bill stouter, triangular in lateral profile, relatively deeper at base; depth at frontal antiæ equal to three-fifths to two-thirds the distance from nostril to tip of maxilla, or else the nostrils partly concealed by latero-frontal feathers.

Grallaricula (p. 143).
- ee. Tarsus much more than one-third (sometimes more than half) as long as wing; middle toe, without claw, less than three-fifths as long as tarsus; bill much narrower basally, its width at frontal antiæ equal to little if any more than half the distance from nostril to tip of maxilla; rictal bristles much less than half as long as bill; larger forms (total length about 120-210 mm.).
- f. Tarsus decidedly less than half as long as wing, less distinctly scutellate, the inner edge of the planta scarcely convolute; upper parts squamated

Tarsus much more than one-third (sometimes more than half) as long as wing; middle toe, without claw, less than three-fifths as long as tarsus; bill much narrower basally, its width at frontal antiæ equal to little if any more than half the distance from nostril to tip of maxilla; rictal bristles much less than half as long as bill; larger forms (total length about 120-210 mm.).
Grallaria (p. 146).

- g. Tail at least half as long as wing; rictal bristles distinct.
- h. Bill stouter; tarsus more than half as long as wing; coloration more varied, the pileum and hindneck rufescent in contrast with olive of back, etc., the under parts white striped laterally with brown
- g. Tail at least half as long as wing; rictal bristles distinct.
- ff. Tarsus at least half as long as wing, more distinctly scutellate, the inner edge of the planta distinctly convolute; upper parts not squamated.
