Obs. It was LiN'N^us's mistaken use of the name pelamis for 

 the Ronito, which had already been described by OsBECK under a 

 binomial specific name (Scomber pulcher), that caused the blunder 

 of which liRLN.NlCH was guilty, and the confusion which existed until 

 CuviER solved tlie question. The Bonito was not known to the old 

 writers, while the Pelamis, even if the name was originally given to 

 young Tunnies, was well described by Rondklet and received the 

 name pelamis from Salvia.vus and that of pelainys from Willuohby. 



Sciindinavian Fishes. 



It was also called pelamide by the Italians and in Marseilles. The 

 disadvantages of having the same specific name within two genera 

 so closely related to each other as Orcynus and Sarda, especially as 

 the names of Bonito and Pelamis are often confounded, need no re- 

 mark. But they are a natural consequence of the current laws of 

 nomenclature, and can only be removed by the recognition, in defi- 

 ance of these laws, of Bloch's specific name, Sarda medilerranea, 

 as Jordan and Gilbert have proposed. 



The Stripe-backed Pelaiuis, Avhich attains a length 

 of from 5 to 7 dm., is distinguished externally from 

 the preceding species chiefly by the straight, or even 

 slightly concave, upper margin of the first dorsal fin, 

 but there is no anterior flap-like elevation of this fin 

 in either species. The second dorsal and the anal fins, 

 too, are lower, the pectoral shorter and the hind mar- 

 gin of the preoperculum, as well as of the whole gill- 

 cover, more rounded, thus causing a resemblance, espe- 

 cially in the preoperculum, to the next genus and 

 species. The head, too, is longer, the eye being com- 

 pletelv situated in the front half of its length. The 

 jaw-teeth are pointed, but somewhat compressed, and 

 thus remind us of Scomberomonis. In the front of the 

 lower jaw there are a few (from 2 to 4) large teetli 

 which are almost distinct canines. Tlie membrane on 

 the margins of the preoperculum and operculum is
