73 



the toes longer than the sole. A distinct wart at lieel. Oalcar slender, 

 distinct, about equal to free border of iuterfemoral membrane, terminat- 

 ing in a small but distinct lobule and noticeably keeled along jjosterior 

 edge. The keel is supported by 1 to 3 cartilaginous processes. 



Fur and color. — Except for its unusual extension on the back of the 

 uropatagium the fur shows no peculiarities in distribution. 



In color the fur is pale yellowish white throughout. The ears, muzzle, 

 and chin are dark brown in strong contrast. Membranes light brown 

 with pale edges. 



Measurements. — See table, page 74. 



Specimens examined. — Total number 13, from the following localities: 



Kansas: Trejjjo County, 6. 



South Dakota: Carroll Draw, Pine Ridge Indian Reservation, 7 (skins Am. 

 Mus. Nat. Hist.). 



General remar Is. — My otis calif ornicus ciliolahrnm is a pale, whitish, 

 race of M. caUfornicus, presenting the opposite extreme from J\f.c. can- 

 rinus. Except in color, I can not find that it differs in anj^ constant 

 characters from typical calif ornicus. The specimens from Grant County, 

 N. Mex., referred to in the original descrii)tion of M. c. ciUolahrum are 

 undoubtedly true calif ornicus^ as nre those from Death Valley referred 

 to this subspecies by Dr. Harrison Allen.
