Fam. XVI. PHYTOTOMIDÆ, or PLANT-CUTTERS.
The peculiar form _Phytotoma_, remarkable for its toothed Fringilline
bill, was associated by the older authors with the Finches. But modern
researches have shown that it is not an Oscinine genus, and that its
true place is near the _Cotingidæ_; indeed, some authors have placed it
within the limits of that family.
Of the four known species of Plant-cutters, all restricted to South
America, one is a well-known denizen of the Argentine Republic.
