« Ten specimens. 



'' Specimens from Nicasio, Marin County, are, as a rule, quite as deeply colored 

 as T. b. calophonus, in fact but for their different measurements (which are those of 

 T. b. spilurus) would be referable to that form. One example from Nicasio, in Mr. 

 Brewster's collection (no. 20068), is, on the other hand, grayer even than T. b. dry- 

 moecus and can only be regarded as abnormal.
