Vespertilio, Linneeus, 1758). 
The specific name Vespertilio murinus, Schreber, 1775, is 
preoccupied by V. murtnus, Linneus, 1758. As already 
pointed out by Nilsson, it must therefore give way to 
Vespertilio myotts, Bechstein, 1791. The common, large, 
38-toothed bat of Central and Southern Europe is then 
Myotis myotis (Bechstein).

II. The Genera Pipistrellus and Pterygistes. 
It has already been shown that one of the several genera 
commonly associated as subgenera under the name Vesperugo 
must take the name Vespertilio. It remains to show that the 
name Vesperugo cannot be used in any sense. 
As originally defined by Keyserling and Blasius, the genus 
Vesperugo included twelve species: serotinus, discolor, 
Nilssoni, Savit, leucippe, aristippe, noctula, Leislert, Kuhlii, 
albolimbatus, Nathusii, and pipistrellus. These were arranged 
in two subgenera—Vesperugo, including the #84-toothed 
species, and Vesperus, those with 32 teeth. The subgenus 
Vesperus is exactly equivalent to the restricted genus Vesper- 
tilio, Linneus, to the genus Hptesicus, Rafinesque, and to the 
genus Cnepheus, Kaup, each of which antedates it. Aside 
from this, however, it would be necessary to find the type of 
the genus among the species referred by the authors to the 
typical subgenus. ‘I'hese represent two modern groups— 
the first consisting of noctula and Leislert, the second of the
