Villiform teeth in broad hands in the jaws, the outer series somewhat 

 enlarged and widely set, in narrower bands on the palatines and tongue, and 

 in a triangular patch on the head of the vomer. 



Cheeks, temples, and upper part of opercles scaly, the rest of the head, 

 the nuchal ridge, and the breast naked; preorbital and preopercle crossed by 

 numerous mucous canals; nuchal canal indistinct, not nearly reaching to the 

 dorsal. Lateral line gently curved to below the 9th dorsal ray. the length of the 

 curved section 1-15 in that of the straight, which is armed throughout with 38 

 strongly keeled spinigerous scutes, the widest on the peduncle 2-3 in the eye- 

 diameter. 



Dorsal fin vi. i 21 rays; spinous dorsal moderate, originating well behind 

 I he base of the pectoral ; procumbent spine concealed ; spines flexible, 3rd longest, 

 2-2 in the length of the head. Soft dorsal originating midway between the tip 

 of the snout and the root of the caudal fin, the anterior ray produced as a filiform 

 appendage, extending when depressed to the end of the proximal third of the 

 upper caudal lobe and 1-7 in the length of the body; 2nd ray one fifth shorter 

 than the head, those behind it gradually decreasing to the 7th; last ray slightly 

 produced. Caudal fin deeply and widely forked, the upper lobe the longer, 

 2-!) in the length of the body. Anal fin with ii, i 18 rays, originating below 

 the 9th dorsal ray ; free spines short and weak, the 2nd the longer, 2-15 in the eye- 

 diameter and 8-7 in the 1st ray. which is slightly filamentous, as long as the 

 head, and reaches when depressed to the 16th ray. Pectoral with 21 rays, its 

 length 2>55 in that of the body and two fifths more than that of the head; -1th 

 ray longest, extending to above the 5th anal ray. Ventral rather small; inserted 

 behind the pectoral-base, its length 2-7 in that of the pectoral and 1-9 in that of 

 the head; outer ray longest, reaching midway to the 3rd anal ray. 



Gill-rakers stout and of moderate length, 5+19 on the anterior arch, the 

 longest a little shorter than the gill-fringes and 7-5 in the length of the head. 

 Vent midway between the origin of the ventral and the second free anal spine. 



Upper surface pale olive green, shading into silvery on the sides ; abdomen, 

 breast, and lower surface of head milk-white; an obscure dusky spot behind the 

 eye and another upon the opercle, the two connected by a narrow dark blue 

 band, which is produced backwards below the lateral line to above the middle 

 of the pectoral. Short rays of soft dorsal tipped with lavender; upper lobe of 

 caudal dull violet tipped with blackish, lower grayish tipped with smoky brown; 

 other fins colorless, {gracilis, slender.)
