In the present instance, the figure and fin-ray formula of 

 Cuvier are given ; to which the description of Mr. Couch's

 the correctness of the junction here proposed. The number 

 of fin-rays are, according to 



Cuvier.

 covering of the gill-covers elongated posteriorly ; seven rays 

 in the gill membrane. Body and head covered with large 

 scales ; lateral line gently curved. Dorsal fin single, long, 

 expanding towards its termination, with eleven spinous rays, 

 the first short, and seventeen soft rays, the two last from one 

 origin. Pectoral fin round, nineteen rays ; ventrals fastened
