is distinguished from its congeners by the following combination of characters: Vertebrae ca. 90 (holotype) to 95; dorsal-fin origin associated with vertebrae 8-9; caudal-fin length 25.7-30.2% SL; suborbital pores 6 + 0; gill rakers 3 + 12-15 = 15-18; P 17-18; minute papillae covering dorsal region of head and lips in adults.

<paragraph lastPageNumber="8" pageNumber="7">Variation in cephalic pore patterns between these two juveniles and the 248 mm SL adult holotype are noteworthy. All three specimens with suborbital pores 6 + 0 and eight preoperculomandibular pores. However, the holotype has a median occipital and an interorbital pore, both absent in the juveniles. The postorbital canal of the holotype has four pores on the right and three on the left, whereas one juvenile has two pores on both sides, the other has three on the right and two on the left. Caudal fin relatively long. Caudal skeleton with one epural, four upper hypural and 45 lower hypural rays. Dorsal-fin origin retrograde, associated with vertebrae 8-9 in juveniles, but snout short, thus predorsal length not diagnostic. No free dorsal-fin pterygiophores. Anal-fin origin associated with ultimate precaudal vertebrae, with four pterygiophores inserted anterior to haemal spine of first caudal vertebra. Last dorsal-fin ray associated with third preural centrum, last anal ray associated with second preural centrum. Holotype with ventrolateral and mediolateral branches of lateral line, juveniles with very indistinct lateral line neuromasts of both branches. Scales in smaller specimen on tail and anteriorly on dorsum to about half an eye diameter behind dorsal-fin origin, absent on fins and abdomen in larger specimen. Gill slit extending ventrally to opposite lowermost pectoral-fin ray or slightly lower. Minute papillae described in adult holotype not developed in these juveniles, but flat, round clumps of thickened tissue present on snout and interorbital region are interpreted as precursors to adult, wart-like papillae.</paragraph>

Remarks. The original description of this species is very brief and I redescribed it on the basis of observations made for me on the holotype by A. E. Gosztonyi (Anderson, 1988). The variation in the cephalic pore patterns seen in the holotype and the two new specimens is not uncommon in species of
