Remarks. — Anderson (1902) regards Vespertilio aegyptiacus Lin- 

 naeus, in Hasselquist, 1757, as being the first name to be applied to 

 these bats. This is erroneous since the description in 1757 is not ten- 

 able but does state that F. aegyptiacus has a tragus, that it is of small 

 domestic mouse size and that the tail is the same length as the body. 

 The name, if it were tenable, would have to be used for Rhinoporrm 

 micnophyllwm.
