Originally Bonaparte adopted the family Theutyes of Cuvier, with 

 the same limits attributed to it hy the great anatomist, but provided 

 the regularly formed family name Teuthididte (1833) or, less correctly", 

 Teuthydidii; (1838). 



In 1810, however, he widely separated the constituents of the old 

 family in the following manner, only special characters being here 

 reproduced :

The AcanthuridiTB contaiu typical representatives of the ftimily so 

 called, but the Teuthididti' do not an&wer at all to the Siganids. The 

 attribute of several dorsal spines and at least a single spine in the anal 

 and each ventral, as well as the single dorsal fin, are descri])tive only of 

 Acanthurids, and not Siganids. The cycloid scales are the only char- 

 acters distinctive of Siganids, and iu 1842 Agassiz, in the seventeenth 



' There is no adjective ruvidus in classical Latin, and it is not evident why scabris 

 should not have been used as the exact e(|uivalent of what Bonaparte meant, instead 

 of a latinized form of the Italian ruvido.
