Diagnosis.—Size large for a Myotis (length 75 to 93 millimeters) ; 
forearm 35.7 to 38.4 millimeters; calear longer than free border of 
interfemoral membrane; ear very long, when laid forward reaching 
from 7 to 10 millimeters beyond snout. 
Description: Head.—Kars large (19 to 20 millimeters in height 
from meatus), thus easily distinguishing this species of Myotis from 
all others occurring in California. Greatest width of ear shghtly 
more than half its length. Anterior border of auricle convex from 
base to a point slightly beyond the middle, thence straight, or nearly 
so, to tip; posterior border slightly concave immediately below tip, 
then gradually convex to base. Tragus long (10 to 13 millimeters), 
slender, and pointed. 
Limbs and Membranes.—Membranes thin and leht. Wings 
attached at bases of toes; third and fifth metacarpals about equal in 
length. Foot slightly less than half length of tibia. Calear slightly 
lobed at tip, and longer than free border of uropatagium. Tail 
slightly longer than forearm. 
Pelage——¥ ur everywhere full and soft. Sides of face scantily 
haired. Anterior border of ear scantily haired on basal fifth. Toes 
slightly haired both above and beneath. Interfemoral membrane 
naked save for basal fifth and a few scattering hairs along ‘‘nerves’’ 
and on free border. 
Color.—Two skins from near Pasadena, Los Angeles County (nos. 
6685, 6953), have ears and membranes dark clove brown; prevailing 
tone of back pale honey yellow, with bases of hairs blackish slate; on 
lower surface of body, outer portion of fur pale olive-buff. One 
specimen (no. 12037) taken July 29, 1910, at Independence Lake,
