thology, p. 141, Wilson says, "This delicate little species is 

 now, for the first time, introduced to public notice. Except my 

 friend Mr. Peale, I know of no other naturahst who seems to 

 have hitherto known of its existence." He further adds, ''It 

 is one of our scarce birds in Pennsylvania, and its nest has 

 hitherto eluded my search. I have never observed it after the 

 20th of August." 



Bay-breasted Warbler, Dendroica castanea (Wils. ). This 

 species was listed by Bartram under the name of Parus peregrinus, 

 the Little Chocolate-breasted Titmouse. Wilson first described 

 it as Sylvia castanea, giving to it its present English name. He 

 speaks of it as a very rare species, passing through Pennsylvania 

 about the beginning of May. The type was evidently obtained 

 in this vicinity. American Ornithology, vol. ii, p. 97. 



Mourning Warbler, Geuthlypis Philadelphia (Wils.). In vol. 

 ii, page 101 of the American Ornithology, Wilson says, " I have 

 the honor of introducing to the notice of naturalists and others 

 a very modest and neat little species which has liitherto eluded 

 their research. I must also add, with regret, that it is the only 

 one of its kind I have yet met with. The bird from which the 

 figure in the plate was taken was shot in the early part of June, 

 on the border of a marsh, within a few miles of Philadelphia. ' ' 



Long-billed Marsh Wren, Telmatodytes palustris (Wils.). 

 Under the name Certhia palustris, Wilson describes this little bird 

 in vol. ii, p. 58 of the American Ornitholog}'. He speaks of its 

 arrival in Pennsylvania and also of its curious song heard " on 

 the reedy borders of the Schuylkill or Delaware in the month of 

 June." 



Wilson's Thrush, Hylocichlafuscesccns (Steph.). Wilson first 

 clearlj' distinguished this species from the Wood and Hermit 

 Thrushes, but unfortunately selected a name, Turdus musiel- 

 inus, which had already been bestowed upon the Wood Thrush 

 by Gmelin. Bonaparte renamed Wilson's bird T. wilsoni, and 

 Stephens, T. fuscescens, the latter having priority. 



Small-headed Flycatcher, Muscicapa minida (Wils. ). This 

 species, not since detected and the basis of Audubon's attack on 

 Wilson and Ord's countercharge, is stated by the latter to have 

 been secured by Wilson near Philadelphia.
