The only detailed account of the manners and 

 habits of this singular animal, is that originally 

 given by Steller in the transactions of the Imperial 

 Academy of Sciences of St. Petersburg, in 1749.

* Resembling in this respect the duckbill animal of New 

 Zealand &c. 



t Cuvier named the genus formed for this species, in 

 honour of Steller; we use his name for the common appella- 

 tion, because we wish to avoid confounding this animal with 

 the Manati by using Pennant's term.
