382 Mr. G. S. Miller, Jr., on the

synonymy of the species is as follows :— 
Vespertilio murinus, Linneus.

The genus Vespertc/io of Linneus contained, as already. 
shown, none of the 38-toothed bats to which the name is 
generally applied. For these bats therefore the name must 
be replaced by Myotis, Kaup, the first based on a member of 
this group. Hence the genus Vespertilio of authors becomes 
Myotis, Kaup, 1829.
