NORTH AMERICAN FAUNA. 



width of tragus through lobe always much less than width at base of 

 anterior edge. 



Membranes. — The membranes are thin and translucent, naked except 

 for a narrow line close to the body. On the uropatagium the furred 

 region occupies the basal fourth dorsally, rather less ventrally, other- 

 wise the membrane is naked except for scattered hairs along the veins. 

 Wings from base of toes. 



Feet. — The foot is moderately large, about half as long as tibia. Toes 

 longer than sole, united by membrane at base to a little beyond middle 

 of x)roximal phalanges, and sprinkled with coarse hairs on dorsal sur- 

 face. Calcar slender, equal to or slightly longer than free edge of inter- 

 femoral membrane, terminating indistinctly or with an ill-defined lobe. 

 Keel rudimentary or absent. 



Fur and color. — The fur is full and soft, but shows no peculiarities 

 in distribution. In color it apparently does not differ from typical M. 

 lucifugus; but too few skins are now available to determine the limits 

 of variation. 



/S'A'itZ/.— The skull of Mi/otis subulatus resembles that of M. evotis so 

 closely that it is impossible to distinguish with certainty between the 

 two. In ili. suhulaU(s the skull is very slightly smaller, but the differ- 

 ence is triiling and intangible. The skull of IT. subulatus does not 

 closely resemble that of M. lucifugus. 



Teeth. — The teeth of Myotis subulatus (fig. 15b) agree in form and 

 relative size with those of M. evotis, and I am unable to find any differ- 

 ences by which to separate them. Thej^ differ, however, in many 

 details from the teeth of M. lucifugus.

General remarl's. — Myotis subulatus may be distinguished from M. 

 lucifugus^ the only species with which it is likely to be confused, by its 

 narrower skull, longer ears, and longer, more sharply pointed tragus.
