188 Gkixnell, Status of the "San Francisco Titmouse." [ tri 



some manner adventitiously colored. The prevailing westerly 

 winds, charged with the gases, soot and dust from the manu- 

 facturing bay-shore districts of San Francisco, sweep across 

 the bay and up over the cities of Alameda and Oakland, with 

 their added contributions, to the hills beyond. It seems to me 

 probable that feathers may be soiled by this dirty atmosphere 

 like the shrubbery and buildings in the same locality. 



Mr. W. O. Emerson has kindly loaned me his series of 12 skins 

 of inornatus from Hay wards. This place is only 14 miles south- 

 cast of Oakland, the type locality of restrictus, but not one of them 

 shows the character of that alleged form. I cannot distinguish 

 these from 15 specimens collected by myself at Palo Alto, 17 miles 

 further south across the bay, nor from 4 skins submitted to me 

 by Mr. H. O. Jenkins who obtained them the past summer in 

 Monterey County. For the want of skins from the immediate 

 vicinity of Monterey we may safely consider the latter, from the 

 headwaters of Big Creek in the coast district south of Monterey, 

 as typical of Bceolophiis inornatus inornatus. Among all these 

 specimens, when seasonal changes are carefully accounted for, 

 there appear to be no locality differences. 



In view of the above considerations, ecologic and otherwise, 

 1 would urge that the so-called "San Francisco Titmouse" be no 

 longer recognized as a phylogenetic race.
