SPERMOPHILA, Swain son. 
Spermophila, Swainson, Zool. Jour. Ill, Nov. 1827, 348. Type Pyrrhulafalcirostris, Temm. (Sufficiently distinct 
from Spermophilws, F. Cuv. 1822. 
Sporophila, Cabanis, Mus. Hein. 1851, 148. Type Fringilla hypoleuca, Licht. 
Ch.—B ill very short and very much curved, as in Pyrrhula, almost as deep as long; the commissure concave, abruptly 
bent towards the end. Tarsus about equal to middle toe ; inner toe, rather the longer, (?) reaching about to the base of the 
middle one ; hind toe to the middle of this claw. Wings short, reaching over the posterior third of the exposed part of the 
tail ; the tertiaries gradually longer than the secondaries, neither much shorter than the primaries which are graduated, and 
but little different in length, the first shorter than the sixth, the second and fourth equal. The tail is about as long as the 
wings, rounded, all the feathers slightly graduated, rather sharply acuminate and decidedly mucronate. Smallest of American 
passerine birds. 
The essential characters of this genus are the small, very convex hill, as high as long; the 
short broad wings, with the quills differing little in length, the outer ones graduated ; the tail 
as long as the wings, widened towards the end, and slightly graduated, with the acuminate and 
mucronate tip to the feathers. 
As the name of Spermophila is sufficiently distinct from Spermopliilus , of prior date, I see no 
necessity for the change of name with Cabanis to Sporophila.
