6 f he only Mexican localities visited by the naturalists of the "Blossom" are 

 Acapulco, Guerrero; Mazatlan, Sinaloa; and San Bias and Tepic, in the Territory 

 of Tepic. The bird found at Acapulco is C. c. flavinuchus, hence the type locality of 

 C. c. chrysogenys must be either Mazatlan or one of the two Tepic localities.
