Abstract
Body length-dependent variability of the 5 following characteristics, commonly regarded as diagnostic, was studied: head length, maximum body depth, interorbital distance, horizontal eye diameter, and snout length. Ray counts in the dorsal, anal, and pectoral fins were analysed. Skeletal bones were described in detail, based on material from 3 individuals. The data obtained served to extend the species description. Functional and evolutionary importance of variability in the characters studied was analysed.
