specimen from Comox, British Columbia, has a wider frontal 

 band than any other example of arizela, but as in size it does not

 arizela have been examined, an asterisk indicating the breeding 

 records : 



British Columbia. — Comox. 



Washington. — Fort Steilacoom* ; Chiloweyuck Depot*; Shoalwater 

 Bay. 



Oregon. — Fort Klamath*; Plush*. 



California. — Owens Lake* ; Carberry's Ranch* ; Stockton. 



Lower California.— Tecate Valley (Mex. Bound. Line)*; La Paz ; San 

 Jos6 del Cabo. 



Sinaloa. — Mazatlan. 



Tepic. — Tepic. 



For comparison, the average measurements of five adult males 

 of each of the three forms here mentioned are appended : 



The writer would here express his appreciation of the kindness 

 of Mr. Ridgway and Dr. Merriam, with regard to the use of the
