PLATE CCCCXXXV. Young. Figs. 1, 2. 



The specimen from which the first figure in the plate was taken, I 

 received from Dr Townsend, who procured it at Fort M'^Loughlin, on 

 the north-west coast of America, in February 1836, having obtained 

 it from Captain W. Bkotchie. The much larger size of this indivi- 

 dual, which was a female, independently of colour, induced me to think 

 that it might be specifically distinct from Cindus Americanus, which 

 it however resembles in its proportions and the texture of its plumage 

 as well as in colom", with the exception of having the head not brown, 

 but of nearly the same tint as the rest of the upper parts. The bill, 

 however, is not larger than that of the individuals represented in PI. 

 CCCLXX, and the dimensions are scarcely superior to those of a 

 specimen described in the Fauna Boreali-Americana. Almost all the 

 feathers of the lower parts are slightly margined with whitish, as are 

 some of those on the wings, and there is a slight tinge of brown on 

 the head. These circumstances lead me to suppose that the present 

 bird is merely an immature individual of the American Dipper, already 

 described (Vol. IV. p. 501). And the smaller specimen, Fig. 2 of the 

 present plate, being in all respects similar, excepting as to size, must 

 also belong to the same species. 



The bill, nostrils, and general form, are as described, which is also 

 the case with the plumage. The greater part of the lower mandible 

 and the edges of the upper have been pale yellow or flesh-colour, the
