DEFINITIONS

GRALLARICULA
(Grallariidae; Ϯ Ochre-breasted Antpitta G. flavirostris) Dim. < genus Grallaria Vieillot, 1816, antpitta; "Genus IX. GRALLARICULA.   Rostrum breve, basi dilatata, rictu parum setoso: alæ breves rotundatæ: cauda brevis: pedes debiles: tarsi graciles, breviusculi; acrotarsiis divisis, paratarsiis integris, unguibus brevibus.   These birds are diminutive Grallariæ, but distinguished by their shorter, feebler bill, the indications of rictal bristles, and short slender tarsi and toes. They appear to form a  transition between Grallaria and Conopophaga. The woodcut represents (fig. 2) the tarsus of Grallaricula flavirostris, which may be contrasted with that of Conopophaga lineata (fig. 3) and Grallaria rufula (fig. 1).   1. GRALLARICULA FLAVIROSTRIS. Grallaria flavirostris, Sclater, P.Z.S. 1858, p. 68.   ...   2. GRALLARICULA LORICATA. Grallaria loricata, Sclater, P.Z.S. 1857, p. 129.   ...   3.

Sclater 1858); "Grallaricula Sclater, Proc. Zool. Soc. London, pt. 26, 1858, p. 283. Type, by subsequent designation, Grallaria flavirostris Sclater (Sclater, Cat. Bds. Brit. Mus., 15, 1890, p. 325)." (Peters, 1951, VII, p. 257). These small birds could be placed in Conopophagidae, near Pittasoma.
