of the plumage, deep brown ; the outer tail-feathers on each side, and the 
edges of the secondaries and wing-coverts, margined with grey. 
Habitat, La Plata, {October.) 
This species differs from Pyr. coronatus or Musicapa coronata, of authors, 
chiefly in its size ; in other respects it is very similar. The admeasurements of 
the latter, for comparison (as given me by Mr. G. R. Gray), are : total length, 
5 inches and 8 lines ; bill, between 9 and 10 lines ; wings, 3 inches and 2 lines ; 
tail, 2 inches and 7 lines ; tarsi, 7 or 8 lines. 
During the summer, this bird was common both near Buenos Ayres and 
Maldonado ; but at the latter place, I did not see one in the months of May, 
June, July, (winter) and therefore, no doubt it is a bird of passage, migrating 
southward during the summer from Brazil. The birds of this and the allied 
genera, correspond very closely in their habits to certain of the Sylviadae of 
Europe ; some of the species frequenting bushes, like the black-cap, {Sylvia atri- 
capilla) ; others more usually the ground, as the robin {Sylvia rubecula) or hedge- 
sparrow {Accentor modularis). Another group {Synallaxis, fyc.) represent those 
European Sylviae, which frequent reeds.

All the plumage chocolate-brown, tinged with red, the latter colour predominating 
on the forehead and lower part of the abdomen ; bill and tarsi, black. 
A single specimen was obtained, and it would appear to be either an imma- 
ture bird or a female.
