The above is a brief account of a species which is very common in the Caribbean sea, and 
a specimen of which Cuvier received from New-York. According to Parra, it is eaten. 
Through inadvertence, Richardson cites the A. hepatus among the fishes of New-York (Faun. 
Vol. 3, p. 86). Schcepff merely states that he saw this species at the Bahamas; but as he 
refers to Catesby, we are enabled to know that he intended the Acanthurus cwruleus, which 
occurs on the coast of Carolina; the hepatus, on the other hand, is only found in the waters 
of the East Indies. Our species is very rare, and can only be considered as a casual visitor. 
I am indebted to Cuvier for the description and figure.
