A variably long, slender tentacle at base of supraocular spine(absent on one side in two specimens, very long, about reachingdorsal origin on one side in one of these specimens) ; shorter, broadertentacles at preocular spine and lower preopercular spines present orabsent. Scales on cheek, chest, anterior part of pectoral base, andinterorbital mostly cycloid; snout and interorbital with small isolatedgroups of small cycloid scales, naked for their greater part. Fourthdorsal spine longest, thence gradually decreasing to penultimate, orfourth to sixth subequal; penultimate spine about three-fourths aslong as last; longest dorsal spine a little shorter than snout and con-siderably shorter than postorbital part of head. Second anal spinemoderately longer than third. (Caudal more or less damaged in thespecimens examined, form of its posterior margin not definitely de-.
