Ammocoetes: estimated max. size at least 175 mm TL (based on adult size), but the largest recorded 148 mm TL. Body proportions, as percentage of TL (based on mean values of four samples totaling 41 specimens measuring 75-143 mm TL): prebranchial length, 7.1-8.8; branchial length, 11.5-13.1; trunk length, 49.5-52.6; tail length, 27.5-28.2. Trunk myomeres, 52-57. Body coloration unrecorded. Extent of pigmentation (- = absence to trace; + = 1% to under 25%; ++ = 25% to under 75%; +++ = 75% or more): upper lip, + (80% of specimens); subocular, - (29%) or + (44%) but the ammocoete in fig. 8 of the original description shows +++; lower prebranchial, - (33%) or + (60%) but the ammocoete in fig. 8 of the original description shows ++; upper branchial, ++ (% not known); caudal fin, + (84%); tongue precursor bulb, - or + (both 47%) or ++ (7%).
