HYPOTHETICAL LIST, 373 



[Vermivora cincinnatiensis (Langdon). Cincinnati Warbler. 



H ehninthophaga cincinnntiensis Langdon, Jour. Cincinnati Soc. Nat. 

 Hist., Ill, No. 2, July, 1880, 119. (Madisonville, Hamilton Co., Ohio.) 



The unique type is regarded as a hj'biid between Vermivora pinus 

 (Linnaeus) and Oporornis fonnosa (Wilson) (cf. Ridgway, Bull. Nuttall 

 Orn. Club, V, No. 4, Oct., 1880, 237.) Dropped from the List in the third 

 edition.] 



Dendroica carbonata (Audubon). Carbonated Warbler. 



Sylvia carbonata Audubon, Birds Amer. (folio), I, pi. 60, 1829. (Orn. 

 Biog. I, 1831, 308.) (Near Henderson, Kentucky.) 



Known only from Audubon's description and plate of two specimens 

 obtained in May, 1811. As a number of his di-awings of birds ol^tained about 

 this time were later destroyed it is possible that the published plate may ha\ e 

 been based to some extent upon memory. 



Dendroica montana (Wilson). Blue Mountain Warbler. 



Stjlvia montana Wilson, Amer. Orn., V, 1812, 113 (pi. 44, fig. 2). (Near 

 the Blue Mountains, Virginia.) 



Known only from the plates of Wilson and Audubon. Not yet satisfactorily 

 identified with any known species. Originally entered as Dendroica {Perisso- 

 glossa) montana. 



Wilsonia (?) microcephala (Ridgway). Small-headed Flycatcher. 



Sylvania microcephala Ridgway, Proc. U. S. Nat. Mus., VIII, 1885, 354 

 [Sept. 17]. New name for Muscicapa tninuta Wilson, Amer. Orn., VI, 

 1812, 62 (pi. 50, fig. 5), nee Gmelin, 1789. 



Known only from the works of Wilson and Audubon whose specimens came 

 from New Jersey and Kentucky respectively. There is some question whether 

 they represent the same species. Wilson's description and small figure have 

 never been satisfactorily identified with any known species Originally 

 entered as Sylvania (?) microcephala. 



icterus icterus (Linnaeus). Troupial. [502.] 



Oriolus icterus Linnaeus, Syst. Nat., ed. 12, I, 1766, 161. (Cayenne.) 



Audubon's record of this species from Charleston, South Carolina, and 

 Bowles's record for Santa Barbara, California (Condor, XIII, 1911, 109) 

 are the only instances of its occurrence in North America and may well have 

 been based on escaped cage birds.
