A number of specimens of birds observed in Sanborn County 

 and collected either there, or near Nemo in Hutchinson County, 

 (also in the Dakota Valley, but lying a short distance south of 

 Sanborn), or in other localities as far or further from the center of 

 distribution of the species, have been submitted to the Biological 

 Survey for verification. The identifications were chiefly made by 

 H. C. Oberholser. It has been thought desirable to append in 

 brackers the known data concerning some of these museum speci- 

 mens.
