This form, with the size and proportions substantially the same 

 as those of redivivus proper, differs very notably in the pallor of all 

 the coloration, being in fact a bleached desert race. Excepting the 

 slight maxillary streaks, there are no decided markings an}-where ; 

 and the change from the pale ash of the general undcrparts to the 

 brownish yellow of the lower belly and crissum is very gradual.

 valley of the Colorado and Gila rivers " in Arizona.
