Hellmayr (Catalogue of the birds of the Americas, vol. 3, 1924, 
p. 135, footnote) writes that a male of this form from Munduapo, 
Rio Orinoco “(about two days by canoe, below S. Fernando de Ata- 
bapo) is more likely to pertain to M. s. multostriata, but the question 
cannot be satisfactorily settled until females come to hand . . ei 
The present female, from farther south still, is definitely of the nominate 
subspecies, having the sides of the head light cinnamon-rufous without 
any dusky streaks. It appears that M. s. multostriata does not cross 
to the north side of the Amazon but is a bird of the forest to the south 
of that river.

The specimen from near Muirapinima appears to be the first record 
of this species outside of the drainage area of the Upper Orinoco and 
is therefore the first one from Brazil. Lest it be thought that it is 
M. surinamensis wrongly named, it may be stated that it has the longer 
bill and black mandible of cherriei. By extending the known range 
southward to the Upper Rio Negro this specimen also helps to settle 
the possibility of cherriei and surinamensis being conspecific; the over- 
lap of the ranges of the two would seem to negative such a suggestion. 
None of the characters separating the males of the two species seem 
to hold except for the pale mandible and shorter bill of cherriei. The 
females are far more distinct. 
One of the March specimens was in molt when collected. - 
A pair collected at Puerto Ayacucho, January 4, 1930, was preserved 
in alcohol. These two are in addition to the skins listed above.
