1 Mockingbird Lake, Riverside Co., July 23, 1922. 
2 El Verano, Sonoma Co., July 11, 1922. 
3 Agua Caliente, Sonoma Co.; nos. 8578-8580 collected as second year larvae, August 27, 1922, meta- 
morphosed in captivity, and preserved on October 27, 1922. 
Range . — Introduced into California. Adult specimens have been 
received at the Museum of Vertebrate Zoology from Sonoma Creek 
at El Verano and Agua Caliente, Sonoma County, and from Mock- 
ingbird Lake, near Riverside. Tadpoles have been received from 
Littlejohn’s Creek at Farmington, San Joaquin County, and from 
a mill pond at Standard, Tuolumne County. The species is reported 
on good authority from Searsville Lake, Stanford University, Santa 
Clara County. It is said to be present in Little Lake, Inyo County. 
(See Storer, 1922, pp. 219-224.) Mr. E. P. Chace of Saugus has 
reported to the writer that he heard bullfrogs and saw T large polly- 
wogs at Resting Spring, Inyo County, in April, 1922. Mr. A. W. C. T. 
Herre, who formerly lived at Los Gatos, has told the writer that there 
were Eastern Bullfrogs in the creek in Los Gatos prior to 1910. The 
species has possibly been introduced in other localities in the State 
and a general increase in area occupied will probably be observed with 
the passage of the years. 
In eastern North America, Rana catesbeiana occurs naturally 
from New r Orleans and northern Florida northward to Montreal, and 
westward to Fort Smith, Arkansas (Cope, 1889, p. 427). The life- 
zones represented in the range there are Lower Austral (the eastern
