operculum feathered for nearly its basal half; lateral feathers of 
throat much lengthened; and tarsus relatively longer. 
Description.—Tail less than wing, but more than nine-tenths of it ; 
middle throat feathers not lengthened, lateral ones much longer, 
forming on each side a conspicuous moustache; tarsus but lightly 
scutellate, sometimes almost imperceptibly ; wing 334 times the tarsus ; 
tarsus about 1% times the exposed culmen ; head not crested ; nuchal 
hairs short, branched; rictal bristles long, reaching about two-thirds 
the length of the bill; bill rather short, broad, much depressed, wider 
than high at anterior edge of nostrils, and much so at base, its height 
at base equal to one-third the length of exposed culmen; culmen 
much ridged, straight or slightly concave, except at decurved tip; 
gonys slightly ascending ; cutting edge of maxilla with several sub- 
terminal notches; nostrils oval, slightly operculate; basal portion 
of operculum rather sparsely feathered to about the middle of nos- 
tril; nasal bristles long and rather numerous. 
Type.—Andropadus latirostris STRICKLAND. 
Although superficially close to Eurillas this group really differs 
very considerably, as above detailed; while by reason of its serrate 
maxilla, broad bill, and roundish nostrils it scarcely needs comparison 
with other genera. 
Its forms are: 
Stelgidocichla latirostris latirostris (Strickland). 
Stelgidocichla latirostris eugenia (Reichenow). 
Stelgidocichla latirostris congener (Reichenow). 
Stelgidocichla latirostris efulensis (Sharpe).

Chars. gen.—Somewhat similar to Andropadus, but nostrils 
rounded oval, little operculate ; bill shorter, broader, much depressed, 
the culmen less ridged; rictal and nasal bristles decidedly longer ; 
tail relatively somewhat shorter. 
Description.—Tail about nine-tenths of wing; throat feathers not 
lengthened ; tarsus scutellate; wing about 4 times the tarsus; tarsus 
about 144 times the exposed culmen; head not crested ; nuchal hairs 
short, branched; rictal bristles long, reaching to between one-half 
and two-thirds the length of the bill; bill short, broad, much de- 
pressed, wider than high at anterior edge of nostrils, much so at 
base, where its height is barely more than half its width, the height 
at base, however, more than one-third the length of exposed culmen ; 
culmen not much ridged, at least appreciably curved from base,
