 Peale stated that a pair were collected and gave measurements for one of 

 each sex. Cassin, however, indicated in his manuscript list that he had but 

 one, and Richmond was able to find only one entry for the species in the

 out trace.

 in Grinnell's study of the type localities of California birds (Univ. California 

 Publ.Zool. 38:260, 1932).
