TYPE SPECIMENS OF BIRDS 49 



(Proc. Acad. Nat. Sci. Philadelphia, p. 29, 1899), remarks without explana- 

 tion: "Type in U.S. National Museum." 



On the reverse side of the red type label are the following comments in 

 Richmond's hand: "Possible type. Cassin says 'Audubon's type' is the 

 bird 'now described', & this is the only Audubon spec, in Nat. Mus. Stone, 

 in his list of types in Phil. Acad. (p. 29) says 'Type in U.S. Nat. Mus.' A. H. 

 Howell compared this specimen with Cassin's description & found them to 

 agree. C.W.R." 



The oldest label carried by the specimen is a piece of heavy cardboard, 

 on which we find, in a semiprinted hand: "Polyborus brasiliensis. /Young. 

 St. Augustin./Plate CLXI. Young./Synopsis p."/. The writing is very dis- 

 tinct from Audubon's cursive script in a series of letters written between 

 1840 and 1846 (now preserved in the Smithsonian archives), but is not 

 strikingly different from the semiprinted addresses on certain of the covers 

 and agrees perfectly with that on the labels of other specimens known to 

 have been Audubon's; the probability of this label's being Audubon's own is 

 therefore very great.
