appearance ; but the bill of the Protonotary is rather stouter, 
and the yellow much deeper, extending farther on the back ; 
its manners, and the country it inhabits, are also different. 
This species is five inches and a half long, and eight and 
a half in extent ; the head, neck, and whole lower parts, 
(except the vent,) are of a remarkably rich and brilliant 
yellow, slightly inclining to orange ; vent, white ; back, 
scapulars, and lesser wing-coverts, yellow olive ; wings, rump, 
and tail-coverts, a lead blue ; interior vanes of the former, 
black ; tail nearly even, and black, broadly edged with blue ; 
all the feathers, except the two middle ones, are marked on 
their inner vanes, near the tip, with a spot of white ; bill, long, 
stout, sharp-pointed, and wholly black; eyes, dark hazel; 
legs and feet, a leaden gray. The female differs in having 
the yellow and blue rather of a duller tint ; the inferiority, 
however, is scarcely noticeable.

This is one of the nimblest species of its whole family, 
inhabiting the same country with the preceding, but extending 
its migrations much farther north. It arrives in Pennsylvania 
about the middle of May, and leaves us in September. I 
have never yet met with its nest, but have seen them feeding 
their young about the 25th of June. This bird is remarkably 
fond of spiders, darting about wherever there is a probability 
* This species is the type of Mr Swainson’s genus Vermivora. The 
specific title is therefore lost, and I see none better than the restoration of 
Brisson’s old one — Ed.
