—— Mag. de Zool. 1837, Cl. 11. p. 21.
My specimen was procured from Maldonado, (June), where it was not common. It frequents the same localities with Synallaxis maluroides, and the two species of Limnornis, and has very similar habits with them. In structure, and in the general shade of its plumage, it is closely allied to the foregoing species, although differing from it in habits.
