This species was found by Dr. Richardson in the fur countries during winter ; they frequent the 

 rivers and estuaries of North America. 



The above bird appears to hold an intermediate station between F. cristata and F. marilla — 

 the crest is smaller than in the former, and larger than in the latter. The female may be distin- 

 guished from the female of the latter by the greater extent of the triangular space at the upper part 

 of the base of the bill, aud from that of Cristata by its larger dimensions.
