TYPE SPECEMENS OF BIRDS 535 



No. 39255, from Sisal, Yucatan, was sent on May 13, 1870, to Jose 

 Salazar Llarregui; No. 39256, from Progreso, Yucatan, has vanished with- 

 out trace. It is possible that both were females, in which case they could 

 not be classed as cotypes. 



No. 44826 cannot now be found, but may have been reentered as No. 

 80084 or No. 177200! Its original number was 82, and this number ap- 

 pears upon the oldest label of No. 74626, but Wood seems to have used a 

 common number for all skins of the same species, and the presence of "82" 

 thus loses some of its importance. 



No. 74626 was, at the time of Ridgway's description, the property of 

 Heniy Bryant, from whom it was borrowed by Ridgway. It did not be- 

 come part of our collection until August 1878, in the course of distribution 

 of the Bryant Collection among various institutions. 



No. 80084 at some time entered Ridgway's private collection and had its 

 original label replaced by one of Ridgway's own, with only partial data 

 transcribed onto it. 



No. 177200 suffered a similar fate at the hands of Henry W. Henshaw 

 (in whose collection it became No. 3149) .

 S[ylvia]. Auduboni J. K. Townsend 



Journ. Acad. Nat. Sci. Philadelphia 7 (2) : 191, 1837. 



=Dendroica auduboni auduboni (Townsend). See Hellmayr, Catalogue 

 of birds of the Americas 8: 390, 1935. 



2909. Adult male. "Forests of the Columbia River"=near Fort Van- 

 couver, Clarke County, Washington. May 31, 1835. Collected by 

 John K. Townsend. Received from Spencer F. Baird, who acquired 

 it from John J. Audubon. 



Stone (Proc. Acad. Nat. Sci. Philadelphia, for 1899, p. 14, 1899) states 

 that the type of Slylvia], Auduboni Townsend is No. 23826 in the Academy's 

 collection, but mentions that three of Townsend's specimens are in Wash- 

 ington. Later (Auk 38:487-488, 1921), Stone vehemently reiterates the 

 Academy's claim to holding the only type. In fact, however, Townsend's 

 name was based upon more than one specimen (both sexes are described!), 

 and there is thus a possibility that one or more skins in Washington may 

 be cotypes. 



Each of the Washington birds has a date on its label. Two of them 

 were taken in 1836 and therefore cannot have been transported to Phila- 

 delphia by Nuttall, who, fide Stone, left Townsend in October 1835. The 

 third, however, was collected on May 31, 1835, and was almost certainly 

 one of the original series and thus a cotype. No. 2909 is, in short, one 



500930—61 35
