" Following Cantor and Giinther others use Teuthis in place of Siganus. The decisions of the 

 International Commission would favor Hepatus as prior to Acanthurus or Teuthis, though not binomial. 

 Any one of these views may he defended, and, until the matter is definitely settled, we may follow custom.
