EREMOPHILA CORNUTA, Boie, (p. 403 )-Sky Lark. 
Plate XXXII. 
The figure on the plate is taken from a specimen collected in Utah Territory hy Captain 
Stanshury, (No. 3702,) and supposed at one time to he the Otocoris occidentalis of Colonel McCall. 
A subsequent examination of a large series of western specimens rendered it very doubtful 
whether there is really any such species, as distinguished hy a white chin and throat from the 
Eremopldla cornuta.
