20 The Ornithology of Chester County 



out all synonyms with the exception of Michener's 

 Warbler, he includes the species given by Barnard 

 and Michener; rejecting only the Gray-cheeked 

 Thrush, and perhaps unconsciously, the Pine Warb- 

 ler; 29 species only rest solely upon the authority 

 of his predecessors, of which 3 seem undoubtedly 

 erroneous as I have already shown. He has added 

 12 new species to the county, most of them with 

 more or less circumstantial annotations; the most 

 important being Leach's Petrel, the only record for 

 the State ; including, however, the White Gyrf alcon, 

 which is not recognized in his later publications; 

 likewise the Migratory Quail, which failed to be- 

 come established. Dr. Warren's continued activity 

 resulted in several subsequent additions, the most 

 notable being Audubon's Warbler, the second East- 

 ern record for this species. 



Dr. Michener's second paper appeared in 1881, 

 long after he had transferred his attention to other 

 branches of natural history. This is a formal list 

 of names compiled from Barnard, Warren, his own 

 earlier list, manuscript of Harry Garrett and a few 

 undesignated species he thought ought to be found in 

 the county; the few annotations being in the form 

 of footnotes. Since he remarks that "the number 

 of species which have actually been found in our 

 county is about 220," and has actually recorded no 

 less than 232 species including two synonyms; all 

 species without satisfactory annotations and without 

 record elsewhere up to this time, must be considered 

 hypothetical; they are the Red-breasted Merganser, 

 Baldpate, Green-winged Teal, Pintail, Canvas-back,
