"Ten specimens in each sex, eight from Jalisco, one from Sinaloa, and one from 

 Zacatecas. Removing from the females the one from Zacatecas, which is exception- 

 ally large in length of wing, tail, and bill, the average of these measurements would 

 be less (wing, 107.4; tail, 58.1). The adult male from Zacatecas, however, is not 

 materially above the average in measurements.
