1 M. Cuvier designated by the term "Murinoid group" those species of 

 Cheiroptera since placed under the genus Vespertilio. In the "Serotinoid 

 group" he placed those species now included in Scotophilus. The names 

 are taken respectively from two well known European species — V. murinus 

 and V. serotinus.
