1918 | Grinnell: A Synopsis of the Bats of California 347 
infusion of species belonging typically to the fauna of the humid 
coast district. 
According to Miller (1897), p. 53) townsendw is the form of 
Corynorhinus macrotis [= rafinesquii] occupying the humid coast 
belt of Oregon, Washington and British Columbia. No examples of 
any form of Corynorhinus which may occupy the humid coast district 
of northern California are available and it is entirely possible that 
the bats from this area may prove to be true townsendi. 
G. M. Allen (1916, pp. 343-347) fails, in his revision of the genus 
Corynorhinus, to recognize the race intermedius and divides the type 
series between the races pallescens and 
townsendii. Of the nine skins of inter- \ 
medius from the type locality which he ~~ / 
examined, he places two as pallescens, 
“not typieal,’’ and the remaining seven 
as townsendii, ‘‘not all typical.’’ <A 
skin of intermedius from Catalina 
Island is listed as pallescens, ‘‘not typi-

Dr. Allen’s paper I am unable to relin- 
quish my opinion that specimens from the semi-humid and semi-arid 
portions of west-central California constitute a recognizable race, 
intermedius. It would indeed be extraordinary if two subspecies 
should have existed in a single colony ! 
Subfamily NycroPHILINAE 
This subfamily, which is represented in North America by but a 
single genus, differs from the Vespertilioninae in the abruptly trun- 
cate muzzle, on the anterior face of which the nostrils open forward 
beneath a distinct horseshoe-shaped ridge or small nose-leaf (Miller, 
1907, p. 284).

of muzzle when laid forward; tragus slender, straight, tapering, a
