SPECIES AND SUBSPECIES RECOGNIZED IN THE A. O. U. CHECK LIST 

 WHICH HAVE BEEN CANCELLED. 



No. 519a. Carpodacus frontalis rhodocolpus (CAB.). This proves to be simply 

 an individual color-phase of C. frontalis (or C. mexicanus frontalis). The 

 Cape St. Lucas specimens, however, which have been referred to this 

 supposed race constitute C. mexicanus ruberrimus KIDGW. (See page 391.) 



No. 576. Peucsea arizonse KIDGW. This proves to be the same as No. 577, P. 

 mexicanus (LAWR.), the range of which is thus extended to Arizona and 

 Sonora.
