OBERHOLSER | THE AVIAN GENUS BLEDA 157 
Pyrrhurus is preoccupied by Pyrrhura Bonaparte’ given to a group 
of Psittacide; and, as there are no synonyms, it has been renamed 
as above. 
An examination of the specimens of Prosphorocichla scandens 
from the Ogobai, or Ogowe, River, Gabun, recorded by Cassin as 
Pyrrhurus pallescens,? and still in the Academy of Natural Sciences 
of Philadelphia, has developed the fact that they are very different 
from true scandens of Senegal. Since Trichophorus pallescens Hart- 
laub? is based on specimens from Gambia, and is identical with 
scandens, the Gabun bird is apparently without a name. Through 
the courtesy of Mr. Witmer Stone it is here described, and called: 
PROSPHOROCICHLA SCANDENS ACEDIS subsp. nov. 
Chars. subsp.—Similar to Prosphorocichla scandens scandens, but 
decidedly smaller; entire upper parts, with sides of head, darker, 
the lores barely paler than the crown, and together with the back 
and scapulars, less ochraceous (more grayish), the rump less tawny ; 
superior wing-coverts and outer vanes of primaries much more 
grayish (less rufescent), barely different from the back ; under wing- 
coverts darker, more grayish; lower parts, excepting the crissum, 
grayish white without buff or cream color, except for a faint tinge 
on the middle of lower breast and abdomen. 
Description.—Type, adult, sex unknown, No. 17,028, collection 
Academy Nat. Sci. Phila.; Ogobai River, Gabun, western Africa, 
1858; P. Du Chaillu. Head brownish slate, lighter on forehead; 
back and scapulars grayish brown; rump more rufescent; upper 
tail-coverts and tail tawny, the shafts paler; wing-quills and their 
superior coverts grayish brown, scarcely more rufescent than the
