« Ten specimens. 



* Five specimens. 



«I am doubtful as to the identification of the specimen from Monterey. It is an 

 old skin in not very good condition, and seems dark enough to be referable to V. h. 

 mexicanus, but the plumage may be adventitiously soiled. At any rate, the locality 

 is decidedly to the northward of Miquihuana, Tamaulipas, where breeding specimens 

 certainly referable to the present form have been taken.
