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 phoebe of Latham, Index Orn. 
II, 1790, 489. This is certainly the 8. fuscus, as shown by the references, and the statement 
that the outer tail feather has the outer web white, which applies only to fuscus.

than the fifth. The primaries more than an inch longer than the secondaries. The upper parts, sides of the head, neck, and 
breast, dark olivaceous brown, the latter rather paler, the head darker. A narrow white ring round the eye. The lower parts 
pale yellowish, deepest on the abdomen ; across the breast tinged with ash. This pale ash sometimes occupies the whole of 
the breast, and even occasionally extends up to the chin. It is also sometimes glossed with olivaceous. The wings and tail 
dark brown ; generally deeper than in S. fuscus. Two narrow bands across the wing, the outer edge of first primary and of the 
secondaries and tertials dull white. The edges of the tail feathers like the back ; the outer one scarcely lighter. Upper mandible 
black, the lower yellow, but brown at the tip. Length, 6.15 ; wing, 3.50 ; tail, 3.05.
