Notes. — This species is most like Colinus godmani but is 

 decidedly smaller and differs considerably in the distribution of 

 the black and rufous ; however, material from intermediate parts 

 of their ranges may prove these differences to be of only subspe- 

 cific value. The females are paler and more distinctly barred 

 on underparts than in C. godmani.
