Two females (one shot I'roni ne.st of two eggs, near Alexandi'ia. Minn.. May 8, 1872,' 

 and the other, also shot Irom nest of two t^\l^'^. near Pelican Lake. Minn., May 21. 1^72') 

 arc entirely absolutely pure white bciu'ath, there being liut the faintest indications of mark- 

 ings in tlie region of the usual abilnmiual licit; even the whole under side of the wing is 

 almost innnaculato. The groimd-c:olor of the upper parts is pale grayish-brown, about 

 Cipially variegated transversely, on the seajjulars and tertial.s, with white. In oik; of them, 

 the sides of the head and neck are pale fawn-color, the "nnistaeho" from the rictus 

 brownish-black in cons])ii'nous eontr.ast ; the upper |iarts an; nearly e(|ually variegated 

 with brown, liglit rufous, and white, the latter predominating posteriorly. The \ipper 

 tail-coverts iu'c immacidate whit<'. The tail-feathers are liglit rufou.s, with pure white 

 shaft.s, eonsideralily mixed with white along the edges of the feather.s, the whit(' consid- 

 erably inrTcasing towai-ds the liase of the tail. Of the subterniinal dusky band there is 

 no trace in one specimen, wliih^ in the other it is indicated by transverse spot.s, while the 

 inner webs along the shafts are nmeh variegated with tr.-nsver.so dusky s])ots. The mah; 

 specimen (shot at Chippewa Lake, itiim., from nest (!) ol' two eggs M.\v 10, 1S72') is 

 consider.ilily darker, nearly like tin' average ])lum.'ige of eastern var. hormliii. Still the 

 white of the lower parts i.s remarkably pure, being of an almost snowy elearness, with- 

 out any trace whatever of an ochraeoous tinpo.
