With regard to the fundamental error about ‘“ Vespertilio 
murinus’’ referred to above, it may be explained that Linnezus, 
speaking in his ‘ Fauna Suecica’ solely of Swedish animals, con- 
sidered that there were two species of Vespertilio only—V. auritus 
with long ears, and V. murinus with short ears. The first is 
Plecotus auritus, and the second is certainly not the large conti- 
nental species commonly so called, which does not occur in 
Scandinavia, but is either the Bat hitherto called Vesperugo 
(Vesperus) discolor, or V. (Vesperus) nilssoni, and in all proba- 
bility the former, the doubt in no way affecting the generic 
changes involved. In the ‘Systema Nature’ the same names 
were used. It is clear therefore that Vespertilio must be adopted 
for the ‘‘ Vesperus” group of Vesperugo, and since it seems on the 
whole advisable that that group should stand as a genus distinct 
from true ‘“‘ Vesperugo,” only two of our British Bats—the Sero- 
tine and the Parti-coloured*—will fall into Vespertilio in its 
new sense. The other members of “‘ Vesperugo,” as a matter 
of priority, must bear the easily remembered name of Pipi- 
strellus. For those formerly called Vespertilio the proper name 
is Myotis. 
Full references are given in the paper by Mr. Miller quoted 
above, as also in the case of Barbastella (1825), which antedates 
Synotus (1839).
