TYPE SPECIMENS OF BIRDS 515 



Vireo nelsoni Bond is a new name, based upon the same type specimen, 

 for V. nanus Nelson, preoccupied when Empidonax {'^LawrencicC') nanus 

 Lawrence, 1875, is placed in the genus Vireo. Bond's name, at its first ap- 

 pearance, in the Proc. Acad, Nat. Sci. Philadelphia, was, in the absence of 

 a definite bibliographic reference, invalid under Article 25 of the Interna- 

 tional Rules of Zoological Nomenclature. 

 Vireo Bellii Audubon 



Birds of America 7: 333, pi. 485, 1844. 

 =Vireo bellii bellii Audubon. See Hellmayr, Catalogue of birds of the 



Americas 8:123, 1935. 

 1926. Adult (sex not indicated). "A short distance below the Black 

 Snake Hills":^Saint Joseph, Buchanan County, Missouri (see Cooke, 

 Auk 27:342, 1910). May 6, 1843 (see Cooke, loc. cit.). Collected 

 by John G. Bell. Received from Spencer F. Baird, who acquired it 

 from John J. Audubon. 

 Cooke, in discussing this skin, observes that "the label on the type speci- 

 men was evidently not written by Audubon himself and whoever wrote it 

 had doubts as to the correctness of the locality." The data on the oldest 

 label were, in fact, written by Spencer F. Baird. 



A putative cotype is preserved in the collection of the Academy of Natural 

 Sciences of Philadelphia, where it is No. 23880; it is a female, received 

 from Edward Harris.
