OBERHOLSER] THE AVIAN GENUS BLEDA 153 
from base; gonys slightly ascending ; maxillar tomium with but one 
subterminal notch; nostrils much rounded, scarcely operculate, and 
if at all, only posteriorly; frontal feathering not extending beyond 
posterior edge of nostrils; bristles of nostrils long and rather 
numerous. 
Type—tIxos phaeocephalus HArTLAvus. 
This is a small group apparently well entitled to generic rank, 
though in most respects very similar to Trichophorus, with which 
of course it has closest affinity. Its long, unbranched nuchal hairs 
and lengthened throat feathers will serve readily to distinguish it 
from other allied genera which have rounded nostrils. 
The only species of this group are: 
Alophoixus phaeocephalus (Hartlaub). 
Alophoixus diardi (Finsch). 
IDIOCICHLA’ gen. nov. 
Chars. gen.—Similar to Bleda, but bill much shorter, its height 
at base decidedly more than one-third of exposed culmen; culmen 
not straight; tarsus at least 114 times exposed culmen. 
Description.—Tail about nine-tenths of wing; throat feathers not 
lengthened; tarsus scutellate; wing about 4 times the length of 
tarsus; tarsus 14%4 to 1% times exposed culmen; head not crested; 
nuchal hairs short (less than 20 mm.), much branched ; rictal bristles 
strong, reaching at least two-thirds the length of the bill; bill stout, 
rather short, compressed, much higher than broad at anterior edge 
of nostrils, about equal in height and breadth at base, its height at 
base more than one-third of exposed culmen; culmen somewhat 
curved; gonys decidedly ascending; mixillar tomium with but one 
subterminal notch; nostrils rounded oval, only slightly operculate, 
and that posteriorly ; forehead feathered to posterior edge of nostrils ; 
nasal bristles long and numerous. 
Type.—Trichophorus notatus CASSIN. 
This group is most closely allied to Bleda, and scarcely needs com- 
parison -with other genera unless possibly with Thescelocichla, 
Alophoixus, and Trichophorus, for all the others with superficial re- 
semblance have linear or lengthened nostrils. 
The species are: 
Idiocichla notata (Cassin). 
Idiocichla canicapilla (Hartlaub). 
1idvoc, distinctus; KivAy, turdus.
