Mr. Ridgway separates this species into two subspecies — M. ful- 

 vifrons rubicundus, from Southern Mexico, and M. fulvifrons pyg- 

 mceus, from North-western Mexico and Arizona, which is said to be 

 smaller and paler below; but the differences do not seem to be 

 material, and I am not able to realize them in the specimens 

 before me.
