DESCRIPTION OF NEW SPECIES OF BATS ALLEN. 



arate from the double crescent form of the cingulum. The cingulum 

 of the third molar of the same series of a double crescentic form. 



Habitat. — Jamaica. The single specimen is a skin in the collection 

 of the National Museum (No. 9397, W. T. March), and was received 

 from Spanishtown. 



I have beeu minute in the description of these new forms for the 

 reason that diagnoses of species have hitherto been too general. Some 

 of the characters, such as the shapes of the terminal phalanges, the 

 patterns of the wing membranes, the depth of the notch in the auricle 

 and the point of termination of the auricular flange or hem have not 

 been used in studying Cheiroptera. Even if the attempt to establish 

 new characters should fail, it is of interest to record these novel details 

 of structure.
