THE MAMMALS OF BERMUDA. 
Paucity of species, as regards mammalian life on oceanic islands, is 
a fact well known to all observers; nor can the circumstance create any ; 
degree of surprise when we become cognizant of the complete isolation 
of such positions from any continent, their small area, and recent 
origin. 
The Bermudas present no exception to this general rule, and there- 
fore the present meagre list will not excite astonishment, especially 
when their peculiar formation and density of population are taken into 
account. 
Order CHEIROPTERA. 
Family VESPERTILIONID. 
SCOTOPHILUS NOCTIVAGANS, Lec. 
‘6 Silver-haired Bat.” 
Only one specimen of this Bat is known to have occurred in the Ber- 
mudas. It was taken alive near Hamilton on the 8th of October, 1850. 
Its geographical range on the North American continent extends, 
according to Allen,* from the Atlantic coast to the Rocky Mountains, 
and as far north as the Hudson’s Bay Territory. 
LASIURUS CINEREUS, Allen. 
“Hoary Bat.” 
According to the observations of my friend, Mr. J. L. Hurdis, of 
Southampton, England, who passed fourteen years upon the islands in 
an official capacity, and during that lengthy period was a close observer 
of the habits of all animals which came under his notice, only two 
species of Bat are known to visit the Bermudas, and that usually in 
the autumn and early months of winter. The present species is observed 
occasionally at dusk during the autumn months hawking about accord-
