southern Sonora are intergrades between C. m. mexicanus and O. m. 

 conspersus, gradually becoming larger and darker to the southward. 

 The average coloration of this intermediate series is almost identical 

 with that of C. m. punctulatus, and many specimens from Arizona 

 have consequently been erroneously identified with that form. At the 

 same time, occurring with these darker birds, sometimes apparently 

 in the same locality, are individuals which seem to be in every way 

 absolutely typical C. m. conspersus. Texan specimens are appreciably 

 paler than the average of those from Arizona, as should be the case 

 when the adjacent forms on each side are light colored, 0. m. aTbifrons 

 being but little if any darker than G. m. conspersus. The series^ of 

 specimens from the Cape district of Lower California is very small 

 and therefore unsatisfactory for comparison, but there seems to be no 

 difference between them and those from southern California and 

 Arizona.
