VIREO HUTTONI MEXICANUS, new subspecies, e 

 MEXICAN VIEEO. 



Adults. — Similar in coloration to V. h. huttoni, but upper parts 

 darker, with the pileum, hindneck, and back duller and grayer olive, 



« Measurements of the type specimen. I have not been able to examine a series 

 of this form, the only other example seen being a young bird from Victoria, Van- 

 couver Island, which differs from a young bird of V. h. huttoni in exactly the same 

 respects as does the adult. 



^ Said to winter in California, but I have not seen a California example referable 

 to this form.
