 Ridgway's notice from those parts. 



Mexico. I have nine specimens of Glaucidium from this 

 country, all with striped heads ; and Mr. Ridgway's synopsis 

 will not quite account for all the differences which I see 

 before me. For instance, G.ferrugineum is said to have the tail 

 "dark brown, crossed by 7-9 continuous bauds of bright 

 rufous, about the same width as the brown ones ; " but of 

 all the nine birds there are only three which have a tail 

 answering to this description, and yet they must all be G. 

 ferrugineum ; for not one has the tail of G. infuscatum, " dark 

 brown, crossed by 6-7 non-continuous bands of white, nar-
