teriorly. Anal fin narrower. Ventral long pointed. 

 Pectoral longish. Lateral line originating from the 

 throat, passing above the ventrals and almost a- 

 long the middle of the tail. Scales very small. 

 Teeth as in the preceding species. 



P. 14.— V. 5.D . 19.— Caudal 14. 



Observations. Body subquadrangular larger to- 

 wards the head, and attenuated towards the tail, 

 where there is no visible keel. The back, head and 

 tail blue, sides and abdomen silvery, a clearer colour- 

 ed band towards the back. 



We never observed more of this species than the 

 individual which is now preserved in the Museum of 

 Natural History at Paris, and the figure in my col- 

 lection of drawings. 



Inhabits the Indian Ocean. 



SCOMBERESOX. Lacepede. 



In this genus the structure of the snout is similar' 

 to that of Belona ; the appearance of the fish itself 

 the same and covered with similar scales, having a 

 earinated range along the venter ; but the latter rays 

 of their dorsal and anal fins are detached into false 

 ones as in the mackerel. 



Monsieur Cuvier remarks that he had only seen 

 a single species from the Mediterranean and the 

 ocean. (The Scombresoces camperien, of Lacepede, 

 v. VI. 3. Esox Saums. Schneider 78.)
