concludes with (E) considerations of the natural affinities of the bird, in the

The publication of this translation by the Swiss Ornithological Society is 
greatly to be applauded, for few were able to read the original, published as 
it was in Danish, though it had already appeared in German, partly in the

the ^Bulletin de TAcademie Imp(5riale de St. P^tersbourg’ (1863). [Cf.

Europe alone, is known with certainty to us, this computation not including 
some specimens mentioned by him.
