All scales strong and adherent, those on body large; those on flanks, on tail, and on belly with spinules arranged in parallel rows; those in predorsal region, on cheek, opercle, and isthmus arranged in more or less diverging rows. Spinules on scales below first dorsal-fin base arranged in 5–6 (7) rows; those on scales below beginning of second dorsal fin arranged in 6–8 rows; rows incomplete (except middle one); middle row of spinules distinctly enlarged and raised, giving appearance of horizontal striations on body surface; spinules in rows gradually increasing in length posteriad. Spinules on tail behind anterior quarter of anal-fin base with spinules more inclined backward and with last spinule of middle row much produced behind posterior margin of scale. Each spinule with prominent lateral buttresses often joined with those of neighboring rows to form low transverse ridges across exposed field of scale (buttresses well-developed and joined with those of neighboring rows even on tail scales). Predorsal scales smaller in size than those on flanks, with similarly erect but shorter spinules, arranged in 3–4 rows. Scales on top of head chiefly with more or less diverging rows of spinules; however, spinules often situated so irregularly that rows becoming indistinguishable; all spinules with prominent lateral buttresses. Area between the orbit, nasal fossa, and suborbital ridge fully scaled, with spinules on scales arranged mostly in clusters. Narrowest portion of suborbital shelf bearing about 4 rows of tightly joined scales between lower rim of orbit and upper edge of suborbital ridge (lowermost row consisting of scales much larger in size). Nasal fossa largely scaleless (few minute spinulose scales present on right side at anterodorsal and anteroventral margins of fossa, and two minute cycloid scales found on left side at anterodorsal margin of fossa). Top of snout densely scaled. Underside of head largely scaleless in preoral region except small area behind terminal scute and lateral quarters of posterior third of preoral length, where densely scaled (
