inches long, has caudal nearly evenly convex behind, -with the upper 

 rays only sliglitly projecting. Anal spines short, graduated, the second 

 the strongest, the third slightly longer, about \ head ; longest rays 

 nearly \ head ; middle ventral rays longest, not nearly reaching vent, 

 f head ; pectoral subtruncate, reaching vent, \\ in head. Scales very 

 strongly ctenoid, rnuuing well up on caudal fin and on membranes 

 of soft dorsal, anal, and ventrals. Color in life: Olivaceous above, 

 whitish below; 7 broad brown bars from back obliquely forward to 

 level of middle of pectorals, these almost obsolete along lateral lino; 

 the color of the bars is not intense and is formed by shadings along 

 the base and margins of the scales ; the anterior bar crosses the nape 

 and is very indistinct; snout and upper part of head with numerous 

 brownish-red spots and lines, 3 or 4 of these parallel and running from 

 eye to snout, the interspace usually light blue; upper lip reddish brown ; 

 tip of lower jaw broadly purplish ; a dark blotch on opercle anteriorly 

 and sometimes a small, dark spot behind eye; lining of opercle and 

 throat lemon yellow; a large jet-black blotch behind pseudobranchiie; 

 spinous dorsal translucent, with indistinct whitish and dusky longitu- 

 dinal streaks ; a large blackish blotch on membrane of last spines imme- 

 diately above fourth vertical bar of sides ; some dark spots on the spines 

 form 2 irregular lengthwise series ; dorsal filaments bright scarlet, the 

 fin usually with light-bluish shading; soft dorsal with a series of bluish- 

 white spots near margin (1 between each 2 rays), 1 or more incomplete 

 series above and below this; the fin is margined with reddish brown, 

 and has usually several series of reddish-brown spots, these most numer- 

 ous posteriorly; some irregular olive-brown spots toward base; a small 

 black spot on base of membrane between eighth and ninth and 1 between 

 tenth and eleventh rays, the former frequently absent ; caudal translu- 

 cent, with irregular cross series of round brownish-red spots, the space 

 between them often with bluish-white spots ; the fin margined above 

 with brownish red; lower lobe whitish, uuspotted; anal white, with a 

 median sulphur-yellow streak and a terminal dark bar; ventrals whit- 

 ish, with dusky areas, often uniform blackish; pectorals translucent; 

 peritoneum silvery. Sexes similar. Rocky shores of South Carolina, in 

 rather deep water; not yet seeu elsewhere, but not rare at Charleston, 

 where the specimen, 9^ inches long, above described, was taken by Dr.

 is not found.)
