* In measuring the ear I place one point of the compass at the tip, and the 

 other at the termination of the outer margin of the ear, whether it terminates 

 as in Murinob suillus at the base of the tragus, or is carried forwards to the 

 angle of the mouth, as in Miniopteris Australis. This I do for the sake of ob- 

 taining fixed points for measuring from in all cases, and also for the purpose of 

 getting the actual diameter of the external ear. 



The length of the head and body is obtained by measuring from the tip of 

 the nose (the head being fully extended) to the posterior margin of the anus. 

 For the purposes of comparison I have, in this case, determined the expanse 

 of wings by Mr. Tomes's method which see under his description of Miniop- 

 teris Australis, loc. cit.
