Cuvier Ann. d. M. N. H. N. 
The marine animal represented on the present plate, 
and which might very properly be referred to the Lin- 
n®an genus Doris, is by Mons. Cuvier, by whom it is 
described in the work entitled “ Annales du Museum 
National d’Histoire Naturelle,” considered as consti¬ 
tuting a new genus of Mollusca, under the name of 
Phyllidia. It is a native of the Indian seas, and is re¬ 
presented on the plate in its natural size.
