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

 four feet long. — Coryphwna 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
