nearly straight, inner ray 1^ in second, which is 2 in head; first ray 

 branched once, slightly filamentous, other rays branched mnch; second 

 and third anal spines about equal, 3 to 3f in head, relatively larger in 

 smaller specimens, the second stouter; first soft ray 2^ in head; margin 

 of anal slightly concave, the last ray shorter than second spine; upper 

 lobe of caudal longer, the ditference more noticeable in the smaller speci- 

 mens, \\ to \\ in head, middle rays 1;' in upper; pectoral scaly at base 

 only, other fins, except spinous dorsal, more or less completely scaled, a 

 narrow sheath of scales on sides of dorsal and anal, supplementary scales 

 slightly developed in axil of ventrals; least depth of caudal peduncle \\ 

 to If in the length from below end of dorsal, its length being equal to 

 middle caudal rays; lateral line and rows of scales above it concentric 

 with back, scales below lateral lino in horizontal rows. Color in alcohol: 

 Dark olive above, lower sides more or less silvery, the larger specimens 

 much the lighter; a dark line along each row of scales below lateral line, 

 these rather indistinct in larger specimens; scales above lateral line with 

 dark centers, these not forming distinct lines; a diffuse dark blotch on 

 scapular region, very faint in the larger specimens; pectorals colorless, 

 other fins punctate, the margins very dark. There is considerable varia- 

 tion in the ground color, the larger specimens being distinctly silvery, 

 some of the suuiller heavily washed with olive and having the scapular 

 blotch more developed. Our specimens differ from Steiudachner's descrip- 

 tion in having a rather shorter maxillary, not reaching eye, narrower pre- 

 orbital, and a blotch on scapular region. They are, however, probably 

 not specifically distinct. West Indies to Brazil ; here described from 5 

 specimens 5| to 7^ inches long, collected at Kingston, Jamaica, by Mr. 

 Joseph Seed Roberts. (Corvina, a synonym of Sokena; forma, form.)
