 =Cinclus mexicanus unicolor Bonaparte. See Hellmayr, Catalogue of

 2862. Adult (sex not indicated). "Oregon?" Collected by John K. 



Townsend. Received from Spencer F. Baird, who acquired it from 



John J. Audubon. 

 The oldest label carried by this specimen is Baird's; its data are: "Cinclus 

 americanus Sw./2862. J.K.T./N/Oregon?" ("N" was Baird's symbol for 

 skins presented him by Audubon) . 



Cinclus Mortoni was based by Townsend upon one specimen, a male, 

 "shot by Captain W. Brotchie, near Fort McLoughlin [McLaughlin], on the 

 N.W. coast of America, in latitude about 49° N." Cinclus Townsendi (see 

 below) was similarly named by ToAvnsend from a female procured "in the 

 vicinity of Fort Vancouver." Since, on Townsend's own authority, we know 

 that he possessed but two examples of the dipper, and Baird obtained from 

 Audubon two skins of Cinclus, each putatively collected by Townsend, one 

 is forced to consider the possibility that our Nos. 2861 and 2862 are the 

 types of Cinclus Townsendi and C. Mortoni. 



It may be said at once that neither description agrees with either of these 

 skins, but, in fact, such statements as "belly . . . slightly banded trans- 

 versely with blackish" and "the whole inferior surface of the body . . . 

 banded transversely with blackish" do not fit any specimen of the American
