are established upon them. They are generally goad in taste, the flesh being 
fatty and delicate in structure. 
In 1803 Lacépède created a new genus Scornberomorus for a fish of this 
genus, by examining an inaccurate copy of a sketch by Plumier, which 
represented the two dorsals as if they were connected together. But afterwards 
Lacépède found that his Scornberomorus plumier ii was a synonym for Scomber 
regalis 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 Lacépède is quite inappropriate for any fish of the Cybiidae. The 
diagnosis is written as follows :— 
“ Une seule nageoire dorsale ; de petites nageoires au-dessus et au-dessous 
de la queue ; point d’aiguillons isolés au-devant de la nageoires du dos ”. 
I have found the five following species in our waters. Though Jordan 
and Richardson (29) mention the name of C. kuhli in their catalogue of 
Formosan fishes, I was unable to find the species. 
Key to the Japanese species of the genus Cybium.
