Dorsale stekels (totaal) : 9; Dorsale zachte stralen (totaal) : 10; Anale stekels: 3; Anale zachte stralen: 6. This species is distinguished from its congeners by the following cahracters: brown-colored lateral line; mean interorbital width 4.1% of SL (vs. 5.2-6.9%); mean snout length 8.9% of SL (vs. 9.8-11.1%); mean orbit diameter 4.5% of SL (vs. 5.4-7.3%); mean mandible length 15.7% of SL (vs. 19.9-21.6%); differs from C. undecimalis by the number of circumpedancular scales 18-22, usually 19-21 (vs. 22-28, usually 24-27) (Ref. 121036).
This species was observed in the more saline waters, close to the outlet channel of the lagoon to the sea, as confirmed by local fishermen. It was also found in the center of the lagoon. None of the specimens collected from the lagoon were preserved, and these were lost, but a picture of the largest individual (53.55 cm SL) was taken (Ref. 121036).
