This specimen was a female; the tongue was thick and fleshy,, 
armed on each side with thirteen strong, bony teeth, exactly similar in 
appearance, as well as in number, to those on the tongue of the Snow 
Goose ; the inner concavity of the upper mandible was also studded- 
with rows of teeth. The stomach was extremely muscular, filled with 
some vegetable matter, and clear gravel. ae 
With this, another was shot, differing considerably in its markings, . 
having little or no white on the head, and being smaller; its general 
color, dark brown, intermixed with pale ash, and darker below, but ev- 
idently of the same species with the other. <<

Tis is rather a scarce species on our coasts, and is never met with 
on fresh-water lakes or rivers. It is called by some gunners the Sand 
Shoal Duck, from its habit of frequenting sand bars. Its principal 
food appears to be shell fish, which it procures by diving. The flesh 
is dry, and partakes considerably of the nature of its food. It is only. 
seen here during winter ; most. commonly early. in the month of Mareh, 
a few are observed in our market. Of their principal manners, place, 
or mode of breeding, nothing more is known. Latham observes, that 
a pair in the possession of Sir Joseph Banks were brought from Lab- 
rador. Having myself had frequent opportunities of examining both 
sexes of these birds, I find that, like most others, they are subject, 
when young, to a progressive change of color. The full-plumaged 
* The Prince of Musignano places this bird among the Fuligule.- I have had no 
opportunity of seeing the bird itself, and cannot therefore speak, from examination, 
as to its station. It seems a true Sea Duck, and agrees in general habits with the 
Seaups and Pochards. — Ep. :
