 Artedi, or rather by Rondeletius, has supplied Cuvier with the 

 type of a peculiar family, in which he has retained the generic 

 characters of Linnaeus, viz. one dorsal fin with soft rays, and 

 a second one, which is rudimental and only adipose. Cuvier 

 places this family in his order Malacopterygii Abdominales, 

 between the Silurida: and the Clupece ; and he subdivides it, 

 on just grounds, into a great number of generic sections, which 

 comprehend a vast variety of exotic species. In his work on 

 the fishes of Brazil the author added several new kinds to those 

 which Cuvier established ; and is of opinion that, in the natural 

 classification, it is now absolutely necessary to unite the family
