is quite similar, but with a shorter bill. The species is nearest in 
its relationships to C. virenticeps, but differs in the black maxilla; 
the light base of the lower mandible; the ashy frontal band (seen 
indistinctly on the side of vertex); the much darker, and shorter 
supra-ocular stripe ; the olive green of under parts instead of yellow, 
and of much less extent ; the ashy region behind the eyes, ete.

VIREOLANIUS, Dvsvs. 
Vireolanius, “ Dusus,” Bon. Cousp. 1860, 330. (Type V. melitophrys, 
Dousvs.) 
This group of birds agrees'in all essential generic characters with 
Cyclorhis, especially in the shape and structure of bill, adhesion 
Vireolanius melitophrys, DoBus. (Guatemala.) 
and length of toes, shape of wings, tail, etc., and it is a question 
whether they should not be united. The only difference is in a 
rather less amount of curvature of culmen than in most species, and 
a rather less depth of bill; although in this respect C. nigrirostris 
agrees exactly with Vireolanius. The legs are perhaps less stout. 
The pattern of coloration is quite the same. The type differs most 
from Cyclorhis, and at the same time from the other species asso- 
ciated with it in Vireolanius, in having the tail rather longer than 
the wings, not shorter.
