 Mag. de Zool. 1837, CI. 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.
