Dark phase: Ten males; wing 293-319 (306) ; tail 106-121 
(113); culmen 36.1-39.7 (38.4); depth of upper mandible 
12.2-14.1 (13.1); width of upper mandible 15.5-18.7 (17.2) ; 
tarsus 43-49 (45) ; middle toe and claw 58-68.1 (63.7). 
Light phase: Ten females; wing 304-318 (312) ; tail 107- 
122 (116) ; culmen 34.6-39.1 (36.5) ; depth of upper mandible

tarsus 44-46.7 (45.3) ; middle toe and claw 61.4-64 (62.6). 
Dark phase: Ten females; wing 288-312 (301) ; tail 107- 
116 (112); culmen 34.9-37.8 (36); depth of upper mandible

As shown in the foregoing measurements, the dark phase 
averages somewhat smaller than the light phase.

Gopman—Priocella glaciaioides, xliii, 165, pl. 43. 
In their monographs Mr. Salvin and Dr. Godman treat

Mr. Cassin, in his Wilkes Expedition report, makes the fol- 
lowing statement: “The only specimen in the collection of the
