Description. Body compressed, with its dorsal and abdominal outlines very convex. Scales 

 very large, orbicular, with excentric striae. Lateral line commences at the upper angle of the 

 branchial aperture, descends gently a short distance, when it suddenly curves downwards 

 with a broad curve below the middle of the body, following the abdominal outline to the tail ; 

 the scales of this line contain short and somewliat irregular tubes. Head small, smooth, 

 slightly depressed above, with a range of pores on its upper part. Three flat branchial rays. 

 Mouth protractile, opening somewhat vertically. Upper pharyngeal paved ; lower pharyn- 

 geals with three or four stout white teeth. 



The dorsal fin higher than long, subquadrate, placed behind the line of the ventrals ; the 

 first ray short, simple, not spinous, and closely adpressed to the second, which is longest, 

 and similar in structure to the first ; the remaining rays very ramose, successively shorter. 

 The pectorals broad, placed very low down ; upper ray simple and longest ; the remainder 

 slender, and difficult to be enumerated. Ventrals approximated. Anal longer than high, 

 placed posterior to the termination of the dorsal, excavated on its margin, and composed of 

 one simple and thirteen branched rays. Caudal forked ; the base covered to some distance 

 up with scales. Air-bladder bipartite.

 General hue silvery, mixed with green and blue above, becoming golden on the sides and ab- 

 domen. Irides yellow. Opercles and suborbitals brilliant, lustrous, while, with metallic 

 reflections. Upper part of the head deep brownish black ; back dark green, passing into blue.

This is a savory fluviatile species. It appears occasionally in the New-York market, from
