1920] Swarth: Revision of Avian Oenus Passerella 181 



birds must be conceded to be winter collected examples of stephensi, 

 but it must be recalled that they are but four specimens out of several 

 hundred fox sparrows collected in the same general region, and the 

 conclusion seems unavoidable that they represent unusual occurrences 

 of some sort. When the normal winter home of stephensi is discovered 

 that place undoubtedly will be found to harbor the birds in numbers. 

 Through the courtesy of the authorities of the Carnegie Museum, 

 I have been permitted to examine the type specimen of stephensi, 

 collected by A. W. Anthony, and labelled as taken in the San Jacinto 

 Mountains at 8000 feet altitude. This elevation in these mountains 

 can mean, in this connection, but one place, Tahquitz Valley. In this 

 valley the Stephens fox sparrow is an abundant summer visitant, 

 while the opposite slope of San Jacinto Peak at that altitude is far 

 too precipitous to afford suitable surroundings for the bird. Tahquitz 

 Valley may thus be taken as the type locality of stephensi, fixing it a 

 little more exactly than the general term San Jacinto Mountains.
