The recent discovery of the genus Cinclus in America, furnishes 
an interesting fact in the history of the geographical distribution 
of birds, this genus being one of the twenty-five European, 
enumerated in our “ Observations” as not known to inhabit this 
continent. A specimen from the northern countries, commu¬ 
nicated by Mr. Leadbeater, first enabled us to introduce it into 
the American Fauna; and almost simultaneously, Mr. Swainson, 
in his Synopsis of the Birds discovered in Mexico by Mr. Bullock, 
announced it as occurring in that country, but in no other part, 
as he thought, of America. Judging from his short description, 
(and the species does not admit of a long one) we have no hesi- 
vol. hi.—A
