nois, etc.) and Gulf States (sparingly to South Atlantic States in winter) ; 

 south through Mexico, etc., in winter. 



— . S. semipalmata inornata Brewst. "Western Willet.^ 



No. 290. Colinus graysoni (Lawr.). Grayson's Bob-wMte. 



Explorations in Sonora considerably south of the Arizona boundary, by Lieut. 

 Harry C. Benson, U.S.A., failed to discover any trace of this species, although G. 

 ridgwayi Brewst. was met with in abundance. The likelihood of its occurrence 

 within our limits is thus materially diminished, and it may without much risk of 

 error be stricken from the list of our birds. It occurs abundantly at Mazatlan, but 

 how much farther north its range extends remains to be determined.

C. elegans bensoni Eidgw. Benson's Partridge.^ 



Genus COLUMBIGALLINA Boie, pages 214-215. 



C. passerina varies a great deal with locality, and some of its variations seem 

 sufficiently marked and constant to merit formal recognition. The following forms 

 occurring north of the pai'allel of 18° N. appear fairly well defined : — 



6\ Larger, with bill yellow or red for at least basal half (rarely obscured in dried 

 skins). 

 c^ Back and rump grayish olive, or light grayish brown. 



d}. Much deeper colored, with rather shorter wings and much larger bill, 

 the latter always (?) yellow basally ; wing 3.30-3.60 (3.41), exposed 

 culmen .43-.48 (.47), tarsus .62-.65 (.64). Hah. South Atlantic and 



Gulf States 320. C. passerina (Linn.). Ground Dove.
