In 1817 Ciivier, in the tirst edition of the "Eegne Aniniiir'i adopted 

 the two genera of Forsk;il witli the following naiues: 



Lcs Sidjans. (Auijihacantlnis. Scliu.) 



Les Acaiitlinres. Bl. {Thelitis. L. Ilarpiinis. Forsk.) 



If this means anything, it must be that lie would adopt the name 

 "Theutis" for, or at least limit it to, the ^^Acanthurcs,-' but the meaning 

 is certainly ambiguous; the restriction, however, is not. 



In lS290uvier, in the second edition of the " Regne Animal."- retained 

 the same genera nnder a different guise, viz : 



Les Sidjans. {Siganus. Forsk.) Euro de Commersou : Centrogastcr <le Houttuyn; 



Aiiiph acanthus de lUocli. 

 Les Acanthiires (Acanthiirus. Laccp. et 151.). Harpiirus. Forster. Vnlgairement 



Chirurgieus. 



Here the name '' Thentis^'' or " Tenthis''' is entirely ignored, but Higanus 

 is accepted as the scientitic name of the genus with the limits assigned 

 to it by Forskal. 



In 1822 Fleming ^admitted as genera of the fourth section '^ (d)" of 

 " Scouiberidie," the genera -'140, Amphaeanlhus {Scarus siganus),-'' ^'141, 

 TJientis (T. hepatus),''^ and ''142, Waseus.^^ Theuthis [TeutMs) is thus 

 definitely restricted by specific mention of type to the surgeon-fishes. 



In 1832 Minding, in his " Lehrbuch der Naturgeschichte des Fisches,"* 

 adopted the same two genera with the following names: 



(1) Sidian, Amphaeantlius. 



(2) Felseiitiscli, Teiifhis: ( Tec^/r eine Siipienart bei deu Gr.). 



One species was mentioned, the " Wundarzt, T. chirurgus.'''' 

 In 1833 Bonaparte (then Prince of Musignauo), in the second part 

 of his '^Saggio di nua Distribuzioue metodica degli Animali Verte- 

 brati," gave the following genera under Teuthidida'^' 



158. Sigauus, Forsk. {Bnro, Cornm. Centrofiaster, Houtt. 



Amphacanthus, BJ.) M. Indico. 20. 



159. Tenthis L. {Acanthiirus, Lacep.; Harpurns, Forst.; 



Aspisurus, Lace'p. del.) Atl. Pac. Ira i Trop. 25. 



1. Tenthis, Nob. 



2. Acanthuriis, Nob. 

 S. Scopas, Nob. 



4. Ctenodoii, Nob. 



Both names (Siganus and Teutliis) were thus again used with the 

 limits still retained bv me.
