Remarks. — This race has commonly been united with 

 Thryomanes bewickii charienturus, although Messrs. 

 Thayer and Bangs have shown ^ that it is a readily recog- 

 nizable form. It differs from Thryomanes borickii char- 

 ienturus in its smaller size, particularly of the bill, and in 

 its less heavily barred lower tail-coverts. It was originally 

 described from Cerros Island, Lower California, but oc- 

 curs also on the mainland.
