and the nostril ; outline of those on the sides nearly vertical and reaching but little beyond the beginning of lower edge of bill, 
but as far as those on the side of lower jaw. Nostril large, far forward, its middle opposite the middle of the commissure. 
Male. — Head without conspicuous crest. Head and neck green. Fore part of back black ; beneath salmon color. Wings 
mostly white, crossed by one band of black. Sides scarcely barred transversely. 
Female. — Head with a compressed occipital crest. Head and neck chestnut. Above ashy; beneath salmon colored. White 
of greater coverts with a terminal bar of ashy, (sometimes wanting;) the black of base of secondaries entirely concealed. 
Outer tertials, ash.

The American sheldrake or merganser is abundant during the warmer months, and some 
even remain all winter, leaving their favorite rivers for the open bays. They are found, in 
summer, in almost every small lake and mountain stream, though the males are not so often 
seen there as the females, with their broods of young. In September the young, being fully 
fledged, associate in flocks of several hundreds, in which I have never seen any adult males. 
In January these last are seen in small flocks by themselves, with the head and neck in perfect 
green plumage. — C. 
The common goosander or American sheldrake is very frequently found near Fort Steilacoom 
and upon the Columbia river in Avinter. They are very widely distributed throughout both Ter- 
ritories. I shot a female in the Bitter Root chain of the Rocky mountains in October, 1853, 
where they were quite abundant on the branches of Clark's river. Near Fort Steilacoom they 
are scarce in summer, the greater number, probably, retiring to the recesses of the Cascade 
mountains or further north to breed. — S.

Sp. Ch. — Feathers of the forehead extending on the bill in a short obtuse angle, and falling far short of the end of those on 
the sides ; the outline of the latter sloping rapidly forward, and reaching half way from the posterior end of the lower edge of 
bill to the nostrils, and far beyond those on the side of lower jaw. Nostrils narrow, posterior ; their posterior outline opposite 
the end of basal third of commissure. 
Male. — Head with conspicuous pointed occipital crest. Head and upper part of neck, all around, dark green; under parts 
reddish white. Jugulum reddish brown, streaked with black. Sides conspicuously barred transversely with fine lines of black. 
Feathers anterior to wing, white, margined with black. White of wing crossed by two bars of black. 
Female. — Head with compressed occipital crest; chestnut brown. Body above ash; beneath reddish white. The l)lack at 
base of secondaries exposed ; outer tertials white, edged with black.

I obtained one specimen of this merganser at Fort Steilacoom, where it is not uncommon. 
In habits it closely resembles the preceding species. — S. 
The red-breasted sheldrake is common from September to April, but I have not obtained 
them during summer, though it is not unlikely that they breed in some parts of the territory. 
The shyness of these birds in summer makes it difficult to distinguish this from the last species 
as they fly. — C.
