Type locality Nickajack Cave, near Shellmound, Marion Co., Ten- 

 nessee. 



Distribution Limits of range unknown. It has been taken in Ten- 

 nessee, Indiana, Illinois and Missouri, and will probably be found 

 ultimately in many of our Southern states. 



Description General color dull brown to mouse-gray, somewhat 

 paler and more grayish below, flanks and lower 

 portion of abdomen showing a slight buffy tinge in 

 some specimens; whole number of teeth in upper 

 jaw 18; tragus long and rather slender, similar to 

 that of velifer. 



Measurements Total length, about 4.12 in. (97 to 

 1 10 mm.); tail, 1.65 in. (42mm.); foot, .50 in. (10.5 

 mm.) ; forearm, 1.60 in. (40 mm.) or more; extent (spread of wings), 

 about ii in. (280 mm.). 



Remarks Differs from M. velifer in averaging darker in color and 

 having the wing membrane attached to the feet near the ankle 

 joint and not at the base of the toes as in velifer. 



Very little is known concerning the range of this species, but it has 

 so far been taken in Illinois, Tennessee, Missouri and Indiana. Mr. 

 Howell described it as a new form in 1909, and specimens which have
