The specimen is in poor condition. After decomposition had set in, it had 

 been preserved for a long time in strong alcohol. 

 Habitat unknown, but it is probably Southern California.

Thus the manal formula is 2-10-28-37, the difference between the third 

 and fourth interdigital interspace 18, and is much the same as in A. 

 noveboracensis. 



The measurements of the body and of the metacarpals are within the 

 range of these which can be made on specimens of A. noveboracensis. 

 The second phalanx of the third finger is longer than the second ; the 

 second phalanx of the fourth finger is much shorter than the first ; the 

 second phalanx of the fifth finger is of the same length as the first. In 

 these respects the measurements are in contrast with those of A. novebora-
