Picolaptes (p. 257).
- bb. Bill excessively elongated (more than twice as long as tarsus).

aa. Nostril narrow, distinctly operculate. (Glyphorhynchinæ.)
- b. Bill long, slender, and distinctly (though not strongly) arched or decurved, conspicuously longer than head (about twice as long as tarsus); nasal operculum densely feathered; outer toe distinctly (though slightly) shorter than middle toe. (Drymornithes.)
Drymornis (extralimital).[2]
- bb. Bill shorter than head or at least not distinctly longer, much less than twice as long as tarsus, not distinctly, if at all, decurved; nasal operculum naked; outer toe as long as middle toe.
- c. Bill much shorter than head, the exposed culmen only about two-thirds as long as tarsus; inner webs of remiges crossed by a broad sub-basal band of ochraceous-buff.
- d. Bill very stout, wedge-shaped, with tip of maxilla broad and flattened; nasal operculum very broad. (Glyphorhyncheæ.)
- c. Bill much shorter than head, the exposed culmen only about two-thirds as long as tarsus; inner webs of remiges crossed by a broad sub-basal band of ochraceous-buff.
Glyphorhynchus (p. 274).
- dd. Bill slender, almost subulate, with tip of maxilla narrow, pointed, and slightly decurved; nasal operculum narrow. (Sittasomæ.).
Sittasomus (p. 277).
- cc. Bill nearly as long as head, the exposed culmen as long as (sometimes longer than) tarsus; inner webs of remiges without any cross-band, but uniform cinnamon-rufous (more or less deep) except terminally. (Dendrocinclæ.)
- d. Tail as long as or longer than wing, graduated for half its length, the rectrices conspicuously acuminate and very strongly decurved subterminally (as in Glyphorhynchus and Sittasomus), the attenuated tips distinctly webbed throughout; bill more slender, relatively broader and more depressed basally.
- cc. Bill nearly as long as head, the exposed culmen as long as (sometimes longer than) tarsus; inner webs of remiges without any cross-band, but uniform cinnamon-rufous (more or less deep) except terminally. (Dendrocinclæ.)
