Perissospiza Oberholser, Proc. Nat. Mus. U.S., xxii, p. 227 (1918).
Type, Perissospiza icterioides Vigors.
The name Pycnoramphus Hume, 1874, by which this genus has hitherto been known, is preoccupied by Picnoramphus Rosenberg (Batavier Natur. Tijdschr. Nederl. Ind. xxix, 1866, p. 143) and cannot therefore be used. The bill of this genus differs from the preceding in having the cutting-edge of the upper mandible toothed near the base and in having the inner primaries and outer secondaries rounded at the tips ; the tail is square but is longer than in Coccothraustes.
