westward to the Pacific, northward well into British Columbia and 

 southward to southern California, Arizona and northern Texas, 

 passing into western Mexico and southern Texas in winter. 



Eastward it occurs more or less numerously as far as Wisconsin, 

 Illinois and Missouri, thus overlapping the range of magna through 

 considerable areas. 



As I have no new evidence to offer as to the claims of this bird 

 to specific rank, I have let it stand as a subspecies in accordance 

 with the decision of the A. O. U. Check List Committee, though the 

 excessive rarity of specimens intermediate between neglecta and 

 magna taken in connection with the overlapping of their breeding 

 ranges, seems to me pretty strong evidence of their specific distinc- 

 tion, even though the differences in coloration are slight. 



As already stated, so far as my material goes, it seems that mex- 

 icana (as here restricted) does not occur within the limits of the 

 United States. If my arrangement is adopted therefore, 501a of 

 the A. O. U. Check List will be changed to Stumella magna hoopesi 

 Rio Grande Meadow Lark. 



Measurements in inches of the various races of Stumella are 

 appended.
