a Fourteen specimens. 

 b Sixteen specimens. 



There is some variation in the brightness of the color of the upper parts and deptli 

 of color on the under surface, but the extremes apparently occur among specimens 

 from the same locality, and I am unable to discover constant differences, either in 

 coloration or measurements, between specimens from different geographic areas.
