specimens of the same species in the Paris Museum, and that it was 
the intention of M. F. Cuvier to have described them; he should 
therefore propose the name Cuviert be used to distinguish the spe- 
cies. 
The Secretary also called the attention of the Members present to 
a species of Musk Deer, from Sierra Leone, which had been brought 
from that part of Africa by Mr. Whitfield, who had kindly allowed 
it to be exhibited to the Meeting. In general colour, and in the 
markings on the throat, this species most nearly resembles the Mos- 
chus Sanleyanus, but its body has spots and markings nearly similar 
to those in the M. meminna; it is much larger, however, than either 
of these species, being, in size, about midway between them and the 
M. moschiferus. ‘Yhe chief interest attached to this animal is the 
locality in which it is found, the well-established species of Mos- 
chus being either from the continent of India or the islands of the 
Indian Archipelago. Mr. Ogilby stated that the present animal 
could not be identified with the Moschus Guineensis of Brisson, 
Gmelin, and some other of the older authors; it was therefore ne- 
cessary to give it a new name, and he proposed for that purpose the 
name of M. Aquaticus, in allusion to the peculiar habits of the spe- 
cies which will be described more at length in the Transactions of 
the Society.
