Scomher dekayi Storer, Hist. Fish. Mass. 52. 



Top of lieacl with a conspicuous transparent area, whitish in spirits j 

 eye very large, wider than interorbital area, 4 in head. Maxillary 2f 

 in head ; the distance from tip of snout to angle of mouth 2^ in head ; 

 posterior margin of preopercle straight, and rather less oblique than in 

 pneumatophorus ; the lower margin longer and less rounded than in 

 scomhrm; subopercle very long and narrow ; its greatest width rather 

 less than one-half diameter of orbit ; opercle with a deep emarginatiou 

 opposite base of pectorals. Head 3* in length (without caudal). 



Dorsal fin normally with 9 spines, a 10th sometimes present. 



Scales still larger than in pneumatopliorus ; those on sides in about 

 175 oblique series ; lateral line very conspicuous ; corselet conspicuous, 

 composed of large scales. 



Our specimen from Charleston, S. C, one from Pensacola, Fla., and 

 several from Venice and Genoa, Italy, agree in all respects. 



The Scomher colias of Gmeliu was founded on the fish called by Cetti 

 Lacerto or Colias, and it can probably never be known with certainty 

 which of the three species found in the Mediterranean was thus desig- 

 nated. There can, however, be no doubt as to the species called colias 

 by Eisso. The name may therefore be retained for the present species. 

 Inasmuch as no other name had been given prior to this definition. 



Steindachner considers 8. pneumatophorus as the young of 8. colias. 

 We have specimens young and old of both. We are not yet fully con- 

 vinced, however, that the two forms are really distinct species. 



48. Scomberomorus maculatus (Mitch.) J. & G. — Spanish mackerel. 

 Numerous specimens were observed in the market. 



49. Scomberomorus (?) caballa (C. & V.) J. & G.—King-flsh. 



A large species of Scomberomorus^ known as King-fish, and having 

 inconspicuous dusky spots on sides, is, during the summer months, very 

 abundant off shore, from Cape Hatteras southward. Coasting steamers 

 catch them with trolling lines on every trip, the fish averaging from 3 

 to 5 feet long. A single specimen was seen, about 3i feet long, cap- 

 tured off Cape Lookout, but no description taken sufiQcieut for the posi- 

 tive identification of the species. The fishermen at Charleston are 

 well acquainted with the King fish, though they seldom capture it.
