southwestern Utah and northwestern Arizona, and followed it 

 thence westerly across southern Nevada, where we saw it in the 

 Valleys of the Virgin and Muddy, at the Bend of the Colorado, in 

 Vegas, Pahrump, and Indian Spring Valleys, and throughout the 

 Amargosa Desert. On the California side of the line it was found 

 in Death Valley and its northwest arm (Mesquite Valley), and in 

 Panamint and Owens Valleys. In the latter, both Mr. F. 

 Stephens and Mr. E. W. Nelson recorded it as far north as 

 Benton. The area it inhabits, except the small spot at the head 

 of the San Joaquin Valley, is shown on the accompanying map. 

 The San Joaquin area is omitted because the species is not 

 positively known to breed there — though it probably does so.
