 south through Mexico, etc., in winter. 



. S. semipalmata inornata BREWST. Western Willet. 1 



No. 290. Colinus graysoni (LAWR.). Grayson's Bob-white. 



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 C. 

 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. 



GENUS CALLIPEPLA WAGLER, pages 191-193. 



On page 193, under " c 2 ," insert the following : 



d 1 . Throat with white predominating ; rusty markings on upper parts brighter and 

 more extended, rump more olivaceous, tail less bluish gray, and white spots 

 on lower parts smaller; adult female with crest chiefly light brownish, throat 

 dull white very faintly or narrowly streaked with dusky (mere shaft-streaks), 

 and back distinctly barred with light tawny. Hab. Vicinity of Mazatlan. 



C. elegans (LESS.). Elegant Partridge. 



d?. Throat with black predominating ; rusty markings on upper parts duller and 

 less extended, rump less olivaceous, tail more bluish gray, and white spots on 

 lower parts smaller; adult female with crest uniform blackish, whole throat 

 thickly speckled or streaked with blackish, back nearly uniform gray, and 

 markings of lower parts larger and coarser. Hab. Sonora (vicinity of 

 Campos). 



C. elegans bensoni KIDGW. Benson's Partridge. 2 



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 parallel of 18 N". appear fairly well defined : 



b l . Larger, with bill yellow or red for at least basal half (rarely obscured in dried 



skins). 

 c 1 . Back and rump grayish olive, or light grayish brown. 



d 1 . 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-.4S (.47), tarsus .G2-.65 (.64). Hab. South Atlantic and 



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



<P. Much paler, with rather longer wings and much smaller or more slender
