Var. (a). Vespertilio nitidus macropus (H. Alleu). 



VespertUio macropm 11. Allen, Proc. Acad. Nat. Sci. Pliila., 1866, 288. 



The following is the description of this variety, provisionally de- 

 scribed as V. macropus. Above, fur long', silky, tliree-fonrths black, 

 apical fourth uniform, light russet brown, a small clump at the base of 

 interfemoral membrane. Beneath, same proportion as above, being at 

 base black, at tip grayish- white, pure white at pubis; fur extends later- 

 ally on membrane midway to elbow. Wing membrane attached midway 

 between base of outer toe and ankle joint. In other respects it closely 

 resembles Y. suhnlatus. 



Measurements.* 



Heiglit of ear 6'" 



Heiglit of tragus 3^'" 



Length of humerus 1 ' 4'" 



Lepgth of thumb 3'" 



Length of foot U'" 



Length second joint index finger 1'" 



Expanse 8" 3" 



This form has the light reddish brown color to the fur on the dorsal 

 surface of the body as in the Sonoran varieties of V. nitidus. The foot 

 is very large and the interfemoral membrane triangular below the level 

 of the ankles and the tip of the tail is exsert. As above stated the 

 resemblance to V. suhuJatus {V. gryphus) in this regard is close. V. 

 nitidus macropus 1 believe to be a pedomorphic form of V. nitidus, but 

 owing to peculiarities of environment retains the light yellow brown 

 hues so common in desert living individuals. 



Two other specimens were included in the collection sent me by Dr. 

 Coues at the same time with the foregoing. I named these forms V.
