^ Two specimens. 



Adult males from eastern and western Mexico, respectively, average as follows: 



^ With the same material before me I can not satisfactorily make out Mr. Nelson's 

 S. m. alticola (Auk, xvii, July, 1900, 266) as a sufficiently well-characterized subspe- 

 cies. Mr. Nelson compares it primarily with S. m. magna, but I fail to understand 

 his reason for doing so, its very close relationship to aS'. m. mexicana being obvious. 

 The specimens from the highlands of Guatemala and Chiapas are not, however, in 

 satisfactory plumage, and possibly I may be in error in uniting the supposed form to 

 S. m. mexicana.
