GENUS ICTERIA. Vieillot. 
Bill stout, elongated, convex, curved, entire, with small divergent bristles at the base. Man¬ 
dibles subequal; the edges somewhat bent inwards. Nostrils half closed by an arched 
membrane. Tongue cartilaginous, bristly at the tip. Inner toe free. Wings rounded: 
third and fourth primaries longest; the first scarcely longer than the sixth. 
Obs. This is an exclusively American genus, thus far comprising but one species. The 
name is perhaps objectionable on account of its resemblance to Icterus; but as the species 
on which it was founded has been figured already in five different genera, and as it has been 
generally received by modern ornithologists, it will not in all probability be further disturbed. 
Its place in the systems has also been exceedingly doubtful, and often changed. In the most 
recent systems, it connects the Flycatchers with the Greenlets, but it also forms the passage 
between Merula and Vireo. Its most natural position would seem to be in the abnormal 
group of Conirostres, comprising Pyrrhula, Loxia, &c.
