of which have the basal portions bluish gray; axillars and

circled all around and concealed by this color; back and wing 
coverts grayish-blue with slightly paler edges; rump, similar, 
but darker and more uniform blue, the secondaries have some 
concealed whitish on the inner webs towards the base.

BRANTA NIGRICANS (LAWRENCE). (174.) 
BLACK BRANT. 
Several stragglers of this Pacific Coast species have been 
brought in during the past ten years, by parties visiting the 
Red river valley in the fall shooting season. If they are any- 
thing more than stragglers, they must still be regarded very 
rare. Their identity I can vouch for, from a long familiarity 
with them in Sacramento and Santa Clara counties, California. 
SPECIFIC CHARACTERS. 
Head, neck, and body anterior to the wings deep black, 
passing into dark sooty plumbeous on the rest of the body, 
this color beneath extending nearly to the anus, and above 
shading insensibly into the black of the rump; middle of the 
throat with a white patch extending round on the sides, and 
somewhat streaked with biack; no white On the eyelids; sides 
of rump and base of the tail, with upper and under tail coverts 
concealing the tail, and space across the anus, white; primary 
and secondary quills and tail, black; feathers on the sides of 
the body beneath the wings like the belly, but with white tips.

OLOR COLUMBIANUS (Orv). (180.) 
WHISTLING SWAN. 
Many years ago this species was believed to be a regular 
summer resident of the Red river valley, and not without rea- 
son, for they were occasionally met with as late as the tenth 
of May in spring, and as early as the twentieth of August. 
But these instances have proved to be very rare, and when 
they were reported to me some important observations regard- 
ing their identity were wanted in their later appearance. 
Having never observed them personally, I have been left to the 
conclusion that they were the young of the Trumpeters, a
