accordance with curreut usage will eventually prove tenable, but to 

 decide all such cases in a publication of this kind is manifestly 

 impossible. 



After the current name is given the name which the type repre- 

 sents and the reference to the original description, followed by the 

 catalogue number and data of the type sjiecimen and " parat}'i)es." 



Where specimens are stated to be in the British jNIuseum, U. S. 

 National Museum or other institution, the information is quoted 

 respectively from the Catalogue of Birds, Baird, Cassin and Law- 

 rence, Birds of North America, or the various descriptions of the 

 authors themselves.^ 



Alexander Wilson, 



It is probable that all of Wilson's types that were preserved 

 were deposited in Peale's Museum. The collections there contained 

 were dispersed at auction upon the breaking up of the museum 

 and such Wilson specimens as may have been there are probably 

 lost. 



Two of the types were, however, obtained in exchange by the 

 Academy before the Peale collection was scattered. These are as 

 follows: 

 Buteo latissimus (Wilson.) 



Falco latissimus Wils. Am. Orn.. vi., 1812, p. 92, pi. 54, fig. 1. 



1,551. " Original specimen figured by Wilson." 

 Ictinia mississippiensis (Wilson). 



F'alco mississippiensis Wils. Am. Orn.. iii, 1811, p. 80, pi. 2."), fig. 1. 



2,032. "Original specimen figured by Wilson." 



Thomas Say. 



Say's types collected on jNIajor Long's exj^edition to the Rocky 

 mountains were apparently all deposited in Peale's Museum, and 

 many of them are figured in Bonaparte's American Ornithology 

 and definitely referred to by the Museum numbers. 



As in the case of most of Wilson's types, they have been entirely 

 lost sight of. There is no evidence that any of them came into 

 ])ossession of the Academy." 



* Some data were also kindly furnished by Dr. C. W. Eichmond, of the 

 U. S. National Museum. 



'"Early references to the "Philadelphia Museum" refer to Peale's 

 Museiim, which bore this name after its reorganization, and not to the 

 Academy, as is often supposed.
