located farther forward than usual, the maxillary scarcely extending 

 to the vertical from front of pupil. Teeth rather coarse, in moderate 

 bands on jaws, the outer premaxillary series enlarged. Barbel 

 slender, two-thirds as long as the orbit. Branchiostegals 7. About 

 7 tubercular gill-rakers. 



Eleven scales from origin of second dorsal to lateral line, excluding 

 the lateral line scale. Scales round, with prominent concentric striae, 

 armed with one to five long, slender, recumbent spinules (the number 

 of spinules would probably be greater in larger specimens). The 

 scales on the head and belly are smaller than on the sides. Lateral 

 line rising anteriorly, forming a high curve, as long as the snout plus 

 the orbit. Gular and branchiostegal membranes and inner edge of 

 shoulder girdle naked. 



First dorsal spine short, triangular, compressed; the second spine 

 rather robust, broken in the type, the remaining portion, a little 

 longer than the postorbital length of the head, with ten sharp serra- 

 tions, which are small near the base of the spine ; base of first dorsal 

 about as long as the snout, equal to the interdorsal space; second 

 dorsal low, little more than half as high as the orbital diameter; anal 

 nearly three times as high as the second dorsal, its origin below the 

 middle of the first dorsal base; pectoral 1.4 in head, inserted midway 

 between the verticals from the origin of the dorsal and the insertion 

 of the ventral ; outer ventral ray with a filament reaching the eighth 

 anal ray, the second ray extending about to origin of anal; ventral 

 inserted anterior to the vertical from the origin of the first dorsal a 

 distance nearly equal to the interorbital width. 



Anus far forward, its distance from the base of outer ventral ray 

 about tw^o-thirds its distance from origin of anal; distance from 

 ventral base to isthmus equal to orbit, about 0.9 the distance between 

 the origin of the anal and the base of the ventral. A large naked area 

 about anus, extending forward to between ventrals. 



'Bodj light brown, shading into blackish on belly; branchiostegal 

 membranes brownish black ; gular membrane and opercle with dark 

 punctulations. First dorsal, pectoral, and the bases of a fcAV of the 

 anterior anal rays, dusky ; ventral blackish, except for the light tips of 

 the rays, including the filament ; second dorsal and anal light. Buccal 

 cavity light, a little dusky on roof of mouth, and just within the 

 mandibular series of teeth : branchial cavity dusky under the opercles, 

 with a narrow whitish border on the edge of the branchiostegal mem- 

 branes, whitish on the membrane covering the hyoid a':'ch; isthmus 

 silvery, with large punctulations; peritoneum silvery, mottled with 

 brownish. 



This species is apparently not closely related to any East Indian or 

 Japanese species, but closely approaches two Hawaiian forms: L.
