Occasionally met with amongst the buh'ushes by the 

 borders of the marshes. 



[A South-Brazilian species that might well be expected to 

 occur here. Mr. H. H. Smith obtained examples in Matto 

 Grosso, and Mr. Joyner in Rio Grande do Sul. It is, 

 however, new to the Argentine list. — P. L. S.] 



66. Synallaxis maximiliani (d'Orb.) : Sclater, Cat. B. 

 XV. p. 56. 



(No. 207, ? ?) Fortin Page. November 25th, 1890. 



Not common, and liable to be overlooked owing to its shy 

 and inconspicuous habits. Frequents the margin of the 

 ^'monte duro,^' never leaving it altogether, and hopping 

 about amongst the low bushes. Extremely shy, always en- 

 deavouring to keep hidden behind a branch or other object. 



[The specimen belongs, as might have been anticipated, 

 to S. maximiliani, and not to its northern ally S. torquaia. 

 Azara discovered the species in Paraguay. It is very scarce in 

 collections, and there is only one imperfect example of it in 

 the British Museum.— P. L. S.]
