and in some other points appearing more nearly allied to S. fuscus. Not to multiply synonyms 
unnecessarily, however, I have concluded to adopt the name. The discrepancies in the propor¬ 
tions of the quills may have been caused by their incomplete growth during the moulting 
season. Richardson’s description answers better than the figure, which, with the other on the 
same plate, is wrongly colored. Bonaparte committed a mistake (in which he was followed by 
Audubon and Nuttall) in referring this bird to the Muscicapa plioebe of Latham, Index Orn. 
II, 1790, 489. This is certainly the S. fuscus, as shown by the references, and the statement 
that the outer tail feather has the outer web white, which applies only to fuscus.
