 Audubon along Avith the dupHcates, oi' given to him later by Town- 

 send. 



Dendroica occidentalis (Towns.). 



Sylvia occidentalis Towns. Jour. Acad. Nat. Sci. Phila., vii, p. 190. 



I can find no record of Townsend's specimen of this bird, and 



it is apparently not in the National jNIuseum. 



Geothlypis tolmoei (Towns.). 



Sylvia tolmoei Towns. Appendix to Narrative of Journey Across Kocky 

 Mountain.?, April, 1830, p. .343. Also Jour. Acad. Nat. Sci. Phila., viii, 

 p. 149. 



23,765. Columbia river. J. K. Townsend. Tyj^e. 



Also, three specimens in U. S. Nat. Mus., fiom Baird (2,907, 1,910 and 

 1,861). 



One of these specimens is the type of Sylvia macgillivrayi Aud. 

 (see below), but in a paper in Jour. Acad. Nat. Sei. Phila., viii, 

 p. 159, Townsend insists that his name (tolmoei) should have 

 priority. In this he was correct, though the fact lias been univer- 

 sally overlooked." 



Cinclus mexicanus Sw. 



Cincliis montana Towns. 



Cinclus toicnsendii "Audubon"' Towns. 



These two species are described in the Appendix to Townsend's 

 Narrative, p. 339, Avith reference to Audubon (Vol. iv, pi. 435). 

 The first is based upon a single male, the latter upon a female. 

 The descriptions Avere evidently i)repared liefore Audubon's plate 

 and descriptions appeared Avith the understanding that he Avould 

 adopt the above names. He meanwhile, hoAvever, rightly sur- 

 mised that they were both identical Avith C. americanu.-< Sw. 

 (^ mexicanus Sav. ), and published them under that name ( Orn. 

 Biog., V, p. 303). 

 • The types may possibly be in the U. S. National Museum.
