Type A. cristata. 
Smallest ^Egotheline birds, with small bills, long, rounded wings, long, 
rounded wedge-tails and small feet. 
The bill is apparently very small, but gape large, culmen strongly ridged, 
sides flattened, tip very hooked, lateral edges straight, and entire not toothed ; 
tip of lower mandible decurved and hollow as in Poda/rgus. Nostrils are evident 
as slits on each sides of the culmen placed well forward near tip, hidden by an 
operculum. There are no true rectal bristles, but along the upper edge of 
the culmen bristles have developed, projecting upwards and forwards, and 
becoming very pronounced at the forehead. 
The wing is long and rounded, the fourth primary longest, the third about 
equal to the fifth, the fourth less than the sixth, and the first shorter than the 
eighth. 
The tail is long, the ten feathers broad and rounded at the tips, the whole 
wedge shaped, the outer tail-feather about two-thirds the length of the middle 
pair, which do not extend beyond the next pair. 
The legs long and slender (for the Order), the toes long, the middle claw 
not pectinate. The tarsus is covered with regular scutellse, both in front and 
behuid. 
The preceding diagnosis is based upon the genotype of ^gotheles. Hartert 
admitted a subfamily vEgothefinae, which I here rank as a family, writing : 
“ Nostrils situated near the tip of the bill, obvious and open ; bunches of 
elongated erect loral bristles with long lateral filaments ; no distinct powder 
down patches ; tarsus longer than middle toe ; third and fourth quills longest.” 
Two very distinct groups are included in this : one, the species like cristata, 
the true JSgotheles, as hennetti Salvadori and D’ Albertis, wallacei Gray, and 
salvadorii Hartert, the other crinifrons Bonaparte (= psilopterus Gray), 
insignis Salvadori and pulchra Hartert, etc. These differ from the true 
ASgotheles in being larger, and being differently coloured. As regards colora- 
tion they agree so closely with the species of Batrachostomus that crinifrons 
was described by Bonaparte and also Gray under that genus-name. The
