nostril to tip of maxilla), wholly unfeathered nasal fosse, and very 
plain coloration, without any ornamental plumes on head in breeding 
season. 
Bill subconical, depressed at base, its depth at base of exposed 
culmen equal to less than half the length of exposed culmen and not 
greater than its width at same point, and slightly less than its depth 
at gonydeal angle; culmen depressed basally, then gently convex to 
the tip; gonys as long as or longer than distance from nostril to tip 
of maxilla, straight or very faintly convex, ascending terminally, 
its basal angle prominent; maxillary tomium nearly straight for most 
of its length, but distinctly convex beneath nostril, distinctly notched 
subterminally; mandibular tomium nearly straight, slightly toothed 
and notched subterminally, the tip of mandible acute and very 
slightly recurved; side of mandible ridged along upper portion, 
the ridge broad in middle portion, where the lower. edge forms 
an angle below anterior end of nasal fossa; nasal fossa broad, wholly 
unfeathered, the longitudinal slit-like nostrils in lower edge and 
overhung by a broad, semicorneous convex (in vertical view) oper- 
culum; mandibular rami (measured from gonydeal angle to rictus) 
with about anterior third unfeathered, the malar antia forming a 
rather distinct median angle; anterior edge of loral feathering forming 
a slight convex line from base of culmen to rictus; mental antia broad, 
about on same vertical line with posterior end of nostrils. Wing mod-
