Fam. VII. VIREONIDÆ, or GREENLETS.
Three of the groups of the peculiar American family of Greenlets, allied
to our Shrikes, have representatives within the Argentine Republic. The
genera _Vireo_ and _Hylophilus_ both extend, each in the shape of one
of its South-Brazilian members, into the woodlands of the Paraná; while
_Cyclorhis_, another genus also widely spread over South and Central
America, has two representatives within our area. One of these latter is
well known in the neighbourhood of Buenos Ayres; the other is only found
in the extreme north of the Republic.
