This neat and active little species I have never met with 
in the works of any European naturalist. It is an inhabitant 
of the swamps of the southern states, and has been several 
times seen in the lower parts of the states of New Jersey and 
Delaware. Amidst almost unapproachable thickets of deep 
morasses it commonly spends its time, during summer, and 
has a sharp squeaking note, nowise musical. It leaves the 
southern states early in October. 
This species is four inches and a half long, and six and a 
half in extent ; front line over the eye, and whole lower parts, 
yellow, brightest over the eye, and dullest on the cheeks, 
belly, and vent, wdiere it is tinged with olive ; upper parts, 
olive green ; wings and tail, dusky brown, the former very 
short ; legs and bill, flesh coloured ; crown, covered wfith a 
patch of deep black ; iris of the eye, hazel. 
The female is without the black crown, having that part of 
a dull yellow olive, and is frequently mistaken for a distinct 
species. From her great resemblance, however, in other 
respects, to the male, now first figured, she cannot hereafter be 
mistaken. 
* The Prince of Musignano has never seen this species, but was of opinion, 
that it would prove a Sylvia ; and the specific name being preoccupied, he 
chose that of its discoverer. I have retained his specific name, though the 
reason of the change will not now be available. The services of Wilson, 
however, can scarcely be overpaid, and the reputation of no one is here impli- 
cated Ed.
