In 1803 Lacepede created a new genus Scornheromorus for a fish of tliis 

 genus, by examining an inaccurate copy of a sketch by Plcmier, which 

 represented the two dorsals as if they were connected together. But afterwards 

 Lacepede found that his Scornheromorus plumier'd was a synonym for Scomber 

 rcgalis Bloch ; so that he withdrew the genus afterwards, and omitted it in 

 the index of his work. Moreover the following diagnosis of the genus written 

 by Lacepede is quite inappropriate for any fish of the Cybiidae. The 

 <lit'.gnosis is written as follows : — 



" Une seule nageoire dorsale ; de petites nageoires au-dessus et au-dessous 

 do la queue ; point d'aiguillons isoles au-devant de la nageoires du do3 ". 



I have found the five following species in our watei-s. Though Jordan
