soft rays: 43 - 53;
Vertebrae: 50 - 52. Head rather rectangular in dorsal outline; snout broadly rounded. Frontal fontanelle long and narrow (`knife-shaped'); occipital fontanelle oval-shaped. The `dermosphenotic' and supraorbital bones are fused.

Openings of the secondary canals of the lateral line appear as irregular white spots on the body.
