. Review of American birds in the Museum of the Smithsonian Instution. [microform]. Birds; Oiseaux. CYCL0RHI8. '^X/Wt 885 characters, is very similar to that of Falcunculus (of the Laniadse) of Australia, which it also resembles so much in other characters usually to induce authors to bring the two together, either as ad- jacent genera, or as belonging to closely allied subfamilies. The difference generically between Cyclorhu and Vireolanius is very slight, and I cannot find any real ground of separation. In the latter the bill is perhaps lower and proportionally more elongated; the culmen less curved; the tip longer and more curved, although G. ntgrirostris differs from the other species of Cyclorhis in just these characters^. The nostrils are perhaps more circular and smaller in Cyclorhis. The colors differ somewhatâthe prevailing tints in Cyclorhis being olive green and dull yellow, as in the Vireos, while ill Vireolanius they are deep verdigris green, bright blue and clear yellow (white below in type). If we were to limit Vireolanius to the typeâmelitophrysâthe difference would be rather more appre- ciable. For the present, however, I keep the two gruups separate. Although most of the species of the two genera are strictly South American, I yet give all in detail, in order to furnish a com- plete monograph of the family of Vireonidae.
