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 heen caused by their incomplete growth during the moulting 

 season. Kichardson's description answers better than the figure, which, witli 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 phoebe 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.
