Very .slencier, with sleiiilcr pri/optTi-ular s|iinr Ijrarini; 4 nr .i luJ(^ked spiut'S on u]>pL'r surUu-i', in 

 addition to tlie terminal si)ine; interorliital sjiace very narrow, but grooved; none of tlie dorsal .spines 

 produfed, the second the lon};est, the third and fourth rapidly shortened; head comparatively narrow, 

 its width half its length; snout sh(^rl, inaxillary reaching vertical fnjm front of eye; teeth villiform, in 

 moderate hands, in jaws only ; 2 or '.i cidarged teeth directed backward and forward in the iimer series, in 

 the mid<lle of each mandibular ramus; occipital region flattened, very slightly roughened; preoiienular 

 spine slender, straight, its tip hooked up to form a spine, its upper margin furnishe<l with 4 or f) other 

 spines, retrorsely hooked :;n<l evenly distributed along its whole length, not groupcil at its distal end 

 as usual in tliis genus; lower mai'gin of spine with 2 or 3 minute teeth, irregular in size and jiosilion: 

 the usual strong hooked spine present at base on outer face; preopercular spine reaching half the dis- 

 tance from its liase to opercular margin, its length half diameter of eye. 



None of the dorsal spines )iroduceil or filamentous; upper outline of fin rounded; first spine e(|ual 

 to second or slightly shorter, the tliird ami fourth rapidly shortene<l; ti]is of first, .second, and third 

 s])ines in the declined tin rea<'hing tlie same vertical, which is that of the third ray of secoml d<irsal; 

 soft dorsal comparatively low, the last ray falling far short of base of cau<lal; anal .similar to second 

 dorsal, but higher, its ray slightly passing caudal ba.se, its length sliglitly greater than that of soft 

 dorsal and its insertion a little more |i6sterior; the '■'< middle caudal rays are produce<l to form a tila- 

 mentons process, the total length of caudal ei|ualing length of trunk (without lu-ad); the mend:)rane 

 of inner ventral ray joining jiectoral at the middle of its base; pectoral extending beyond tips of ven- 

 trals, both fins passing front of second dorsal; lateral line single, as usual, and uilli a characteristic 

 beaded appearance; it runs out on caudal lin, aci'ompanying the lifth ray of the upper lobe for a 

 distance equaling two-thirds diameter of eye. 



Color inspirits, dusky olive on top of head and dorsal half of liody, linely vermic\dat(>il with nar- 

 row dusky lines inclosing very small spots of the ground color; lower half of sides of hca<l and body, 

 including branchiostegal meinbrane, tlu' uppci- siirl'ace of ventral tins with the membranes <-onnecting 

 them to l)ase of pectoral, and tlie lower half of laudal lin golden-yellow, marked with bright blue 

 spots and lines, each blue mark with a w ide dusky margin; on lower side of head and trunk the lilue 

 spots frequently coalesce to form lengthwise lines; belly and lower parts generally plain dusky; a 

 quadrate lilack blotch under spinous dorsal, a narrow daik bar under last tlorsal rays, sometimes one 

 also under first dorsal rays, and one on bark of liiil, these dark bars all faintly marked; a blackish 

 streak from eye around tip of snout; spinous dorsal dusky golden, crossed by zigzag blue lines, each 

 narrowly edged with blackish; soft dorsal translucent dusky golden, with irregular bine lines and 

 blot<'hes, arranged for the most part longitudinally. .\nal similar to .second dorsal, the blue lines more 

 oblique, the marginal third of tin lilack; darker markings on caudal arranged in the form of cro.-^s-bars. 



The alxive description is drawn from a male specimen. In females the middle caudal rays are not 

 produced, and no trace of the blue and golden coloration can lie detected. The anal is translucent, 

 w ith a narrow black edge, the median caudal rays are faintly barred, and the spinous dorsal is black 

 with narrow' oblique lighter lines. 



The pectoral rays vary in numlier from Hi to IS; one specimen has but s dorsal rays; otherwise 

 thedor.sal and anal fin rays present no variation.
