[ Chen cserulescens ( LINN.). Blue Goose. This bird has been dropped from the 

 body of the A. O. U. list, and included in the hypothetical list, on account of 

 the possibility, if not probability, that it is a colored phase of Chen hyperborea. 

 The plumage of the specimens that have come under my observation in both the 

 adult and young stages, is certainly very distinct from C. hyperborea, and in my 

 opinion the bird will eventually be declared a valid species, and restored to the 

 list.]
