part of the neck ferruginous ; throat white ; below, white tinged with yellow, 
above grey. — Nest on the margin of fresh water lakes. Eggs 12, white. 
Young like the female. The young males, in female garb, have led several 
zoologists to conclude, that the M. Castor was a distinct species. The inqui- 
ries, however, of an acute and intelligent naturaKst, the late Mr Simmonds, 
(cut off in the prime of life, in the Island of Barbadoes, while actively en- 
gaged in zoological researches), conducted, as I can testify, with great cau- 
tion, enabled him to set the question at rest, by proving an identity in the 
structure, number, and dimensions of the tracheae of the males, the vertebrae 
of the neck, the intestines, and the tail-feathers, Linn. Trans, viii. 268. Mr 
Low mentions a variety of the goosander, in which the whole head, neck, and 
breast were black. — Ork. 132.
