Sp. Coryphcena hippurus L., ROXDELET De Piscib. p. 255, Cuv. et VAL. 

 Poiss. IX. PL 266, BONAP. Faun. ItaL, Pise. Tab. 126, fig. i ; in the Medit. 

 Sea. The dorsal fin is high forwards. The high bony ridge on the top of 

 the skull is remarkable, which extends to the upper jaw ; the superior spi- 

 nous processes also of the five anterior vertebrae are strongly developed, 

 and compressed laterally. This fish becomes fully two, sometimes nearly 

 four feet long. Coryphcena pelagica, Scomber pelagicus L., BONAP. 1. 1. fig. 

 2, with lower dorsal fin and shorter body ; also in the Med. Sea ; some 

 exotic species also, principally from the AtL Ocean on the east coast 

 of South America, as that which is figured by PLUMIER, and copied by 

 BLOCH as Coryphcena hippurus, Ichth. Tab. 174.

 the head.

 Ocean ; this fish attains a size of fully 2'. With respect to the exact species 

 which LINNAEUS described some uncertainty prevails, but the fish here 

 recorded is certainly the PompUus of RONDELET.
