CERCOMACRA
(Thamnophilidae; Ϯ Rio de Janeiro Antbird C. brasiliana) Gr. κερκος kerkos  tail; μακρος makros  long; "GENUS VI. CERCOMACRA.  Statura major: ptilosis magis unicolor: forma validior: rostrum ad basin dilatatum: cauda longa e rectricibus plerumque decem multum graduatis: acrotarsiis divisis, paratarsiis integris.  These birds form a transition between Formicivora and Pyriglena. I have sometimes been inclined to unite them to the latter; but they differ in their broad flattened bill, which in Pyriglena is compressed throughout.   1.
