1918] Grinnell: A Synopsis of the Bats of California 341 
A specimen in the Museum of Comparative Zoology collected in 
the hills back of Lone Pine is stated by G. M. Allen (loc. cit.) to be 
““ pale pinkish buff’ above and nearly white below to the roots of 
the hairs.”’ 
Measurements —Average and extreme measurements in milli- 
meters of a series of ten specimens from the San Jacinto Mountain 
region are as follows: total length, 97.2 (extremes, 92.0-101.0) ; 
tail vertebrae, 47.7 (48.0-50.0); tibia, 18.1 (15.9-19.3); foot, 9.0 
(8.0-11.0) ; forearm, 39.9 (37.5-41.8) ; greatest length of skull, 15.9 
(15.5-16.4).

Synonymy and History—Corynorhinus macrotis [== rafinesquit| 
pallescens was described by Miller (1897b, pp. 52-53) from specimens 
captured in Keam Cafion, Navajo County, Arizona. This author 
regarded pallescens as a race of the Corynorhinus macrotis described 
by LeConte (1831, p. 481). LeConte does not designate a type local- 
ity, but Miller (1897), p. 51) fixes the type locality as the LeConte 
Plantation, in Georgia. G. M. Allen (1916, pp. 838-341) in a revision 
of the genus Corynorhinus states that the species of Corynorhinus 
occurring west of the Alleghanies is distinct from the one described 
by LeConte, and revives the name megalotis of Rafinesque for the 
western animal. Later, Oldfield Thomas (1916, p. 127) finds the 
name megalotis preoccupied, and to have been replaced with the 
name rafinesquii by Lesson (1827, p. 96). 
I have examined certain of the specimens in the United States 
National Museum upon which G. M. Allen based his opinion, and 
coneur with him in recognizing the distinctness of the two species, 
and the nearer affinity of Californian Corynorhinus with the form
