55. Trachynotus caroliiius (Liun.) Gill. — CrevuUc. 



The most highly prized of the fishes of Chariostou. Not brought into 

 the market iu great numbers; known universally as Crcvalle, the name 

 Fompano being seldom used. 



56. Seriola caroliueusis Holbrook. — fack-fish; Amber-jack. 



Seriola carolincnsis and zonafa Holbrook, Iclith. S. C. 72 and 75. 

 Seriola steanisi Goode & Beau, Proc.U. S. Nat. Miis. 1879, 48. 

 (?) Seriola duhia Poey, Memorias do Cuba, II, 228. 



Two young specimens, each about 1 foot long, were obtained in the 

 market, and many very young (3 or 4 inches long) were seen swimming 

 on the surface, on the fishing grounds outside the harbor. These latter 

 had the lateral bands intensely black and very conspicuous. The fol- 

 lowing is the color shown by the two larger specimens, when fresh : 



Back duskj^ bluish, becoming dull white on sides and dull silvery 

 below; five rather faint, broad, dark, half-bars downward from back 

 to axis of body, about as wide as the interspaces ; a light yellow streak 

 from eye back along axis of body to tail, most distinct where it crosses 

 the vertical bars; an irregular yellowish area on lower half of sides 

 anteriorly ; an oblique dusky baud from front of dorsal to eye, and one 

 from eye forward to suborbital ; a broad dusky streak above base of anal ; 

 soft dorsal and anal blackish olive, margined with white, the margin 

 broad anteriorly ; spinous dorsal blackish ; caudal dusky olive ; ventrals 

 silvery white, within dusky yellowish-green ; pectorals with olive tinge; 

 a horizontal blackish streak on opercle. 



This species is exceedingly close to 8. zonata Mitch., the number of 

 fin rays, the pattern of coloration, and the general proportions of head 

 and body being the same. The northern form, zonata.^ has, however, 

 the bauds on the sides appearing jet black at all ages, while in caro- 

 Unensis of the same size these are merely darker shades. Zonata has 

 also the depth much greater, and the body more compressed ; in speci- 

 mens 1 foot long, the depth is contained 2^ times in length (to base 

 of caudal), while in caroUnensis of the same size the depth is of in 

 length. 



A detailed comparison of caroUnensis from Charleston with a speci- 

 }iien of steariisi from Pensacola fails to show any differences. In young- 

 specimens the occiput is more or less sharply keeled, as in zonata, this 

 disappearing with age, the occiput becoming very broadly and obtusely 

 rounded. 



57. Stromateus paru Linn. 



Very common during the summer months. 



Above, light bluish ; below, silvery ; everywhere with iridescent and 

 brilliant silvery reflections; sides often with chocolate-brown blotches ; 

 head light olive, translucent, without silvery reflections above ; snout 

 and sides of head with much coarse, black speckling; anal yellowish- 

 silvery, more oa- less dusky on the falcate rays, everywhere with irides-
