 circled all around and concealed by this color; back and wing

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 sea.son. 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 black; 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. 



Length. 29; wing, 13.80; tarsus, 2.30; commissure, 1.50.

OLOR COLIMBIANI S (Ord). (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
