braiies. The species resembling M,caUformcus in form are all conspic- 

 uously larger. 



In his recent monograph Dr. Harrison Allen uses the name Vesper- 

 tilio nitidus for Myotis californicus. As subspecies of californicus he 

 includes M. yumanensis Vespertilio nitidus macropus^), M, califor- 

 nicus ciliolahrum, and M. lucifugus longicrus (— ' Vespertilio nitidus 

 longicrus^). Vespertilio melanorhinuSy 3> synonym of M. californicus, he, 

 however, refers to ^ V. albescens^ (=M. yumanensis) as a subspecies, 

 ^ Vespertilio albescens melanorhinus.'^ 



MYOTIS CALIFORNICUS CAURINUS subsp. nov. 



Type from Massett, Queen Charlotte Islands, British Columbia. Adult, $ (in alco- 

 hol). No. 72219, U. S. National Museum (Biological Survey collection). Collected 

 in 1895 by J. H. Keen. 



Geographic distribution. — The humid coast district of British Colum- 

 bia, Washington, and Oregon (possibly also of northern California). 



General characters. — Similar to typical M. californicus^ but very much 

 darker in color. 



Ears^ membranes^ feet, and fur. — As in typical californicus. 



Color. — Very deep, frequently almost blackish sepia throughout, 

 slightly yellowish on belly, the fur everywhere blackish plumbeous at

Specimens examined. — Total number, 14, from the following localities:

Washington: Fort Steilacoom, 1; Puget Sound, 1; Tenino, 1. 



General remarks. — In color Myotis californicus caurinus closely re- 

 sembles dark specimens of M. californicus mexicamis. It is readily 

 distinguishable from the latter, however, by its much smaller size.
