OBERHOLSER] THE AVIAN GENUS BLEDA 159 
allies by its much abbreviated tail, as well as by various other ex- 
cellent characters. 
The species are: 
Baeopogon indicator (Verreaux) (= batesi Sharpe). 
Baeopogon clamans (Sj6stedt). 
IXONOTUS Verreaux 
Ixonotus VERREAUX, Rev. et Mag. Zool., 1851, p. 306. 
Chars. gen.—Similar to Prosphorocichla, but nuchal hairs shorter, 
not branched ;.tarsus relatively shorter ; bill shorter, equal in height 
and breadth at anterior edge of nostrils, its height at base about equal 
to one-third the length of exposed culmen. 
Description.—Tail about nine-tenths of wing; throat feathers not 
lengthened; tarsus scutellate; wing about 4% times the tarsus; 
tarsus about 13 times the exposed culmen; head not crested ; nuchal 
hairs very short, not branched; rictal bristles not reaching half the 
length of the bill—but little beyond anterior edge of nostrils; bill 
rather short, somewhat depressed, with height and breadth about 
equal at anterior edge of nostrils, the height less than the breadth 
at base, the height at base about equal to one-third the exposed cul- 
men; culmen curved from base; gonys only slightly ascending ; 
maxilla with only one subterminal notch; nostrils almost linear, 
operculate, the frontal feathering extending only to their posterior 
margin ; nasal bristles few and short. 
Type.—Ixonotus guttatus VERREAUX. 
This genus is apparently most closely allied to Prosphorocichla, 
from which it differs as above stated, but these characters are by 
no means as great as those separating Prosphorocichla from Bleda; 
and Ivonotus, so many and decided are its differences, hardly needs 
comparison with Bleda as here restricted. 
The two species of this group are: 
Ixonotus guttatus Verreaux. 
Txonotus landanae Oustalet. . 
PHYLLASTREPHUS Swainson 
Phyllastrephus Swatnson, Fauna Bor. Amer., 1, 1831, p. 486 (type Le 
Jaboteur, Levaillant). 
Phyllostrophus Sunpevatt, Av. Disp. Tentamen, 1872, p. 20 (nom. 
emend. pro Phyllastrephus). 
Chars. gen—Similar to Ixonotus, but bill longer, more slender, 
somewhat compressed, higher than broad at anterior edge of nostrils, 
the culmen almost straight except at tip; nostrils more oval; nuchal 
hairs much branched.
