54 University of California Piiblioations in Zoology [Vol. 21 



Measurements a/nd weights. — In the accompanying table the 

 average weights of twenty-nine adults are given along with the aver- 

 age measurements of body and skull of thirty-nine adults. It is to 

 be noted that the series from the southern Sierra Nevada, inclusive 

 of both sexes, averages smaller than the comparable series from the 

 Yosemite region. A larger number of specimens from the White 

 Mountains would probably reverse the relation between the sexes 

 shown in that case, since it is hardly likely that the females regularly 

 average larger than the males. 



Distribution area in California. — Transition and Boreal zones of 

 the central and southern Sierra Nevada, from Nevada County south 

 to Jackass Meadow, Tulare County; also occurs on the White, Inyo, 

 and Panamint mountains, in the latter as far east as Telescope Peak. 

 (See map, fig. C.) 



Specimens examined. — Through the courtesy of Mr. E. W. Nelson, 

 Chief of the United States Biological Survey, the writer has been able 

 to examine the four co-types of Neoimna cinerea lucida, as well as 

 representative specimens of Neotoma c. cinerea and Neotonia c. occi- 

 dentalis from near the type localities of each of these forms. In 

 addition to this material from outside of California, the following 

 localities from within the state are represented by specimens of the 

 subspecies cinerea contained in the Museum of Vertebrate Zoology.
