the females of the two species are so 
similar in plumage to each other as scarcely

account for the error. It is well known 
that independent of the labyrinth, the 
trachea of the Goosander possesses two 
enlargements, but Montagu does not ap- 
pear to have noticed in his remarks, that 
the Red-breasted species possess only
