1 It may hereafter prove expedient to separate the birds of the United States from those of Mexico as repre- 

 senting a geographical race. Eight specimens from Mexico (Valley of Mexico, Mirador, Saltillo, Puebla, etc.) 

 are much smaller than northern examples, and with a single exception (an example from Saltillo, Coahuila) 

 have the black bars on the back, etc., much narrower. The extreme and average measurements of this series 

 are as follows : wing 5.90-6.50 (6.13), tail 4.00-4.70 (4.41), exposed culmen 1.20-1.40 (1.30). If separated, the 

 United States bird would have to be called C. cafer collaris (Vio.), the Colaptes collari of VIGORS (Zool. Jour, 

 iv. 1829, 384; Zool. Beechey's Voy. 1839, 24, pi. 9) having been based on specimens from Monterey, Cali- 

 fornia.
