Short Description
Original Diagnosis after ABE, 1966 [3739]: Body nearly naked; skin soft and slippery. Head depressed, wide, nearly rounded anteriorly and large-eyed. Trunk fairly robust; belly more of less swollen. Caudal pedencle little compressed, slightly concave medially behind second dorsal fin, and without lateral keels and precaudal pits. Origin of first dorsal fin behind, or nearly over tips of, pectorals when latter are laid back. Interspace between second dorsal and dorsal lobe of caudal about as long as from orbit to a point between dorsal corners of 1st and 2nd gill-openings (holotype) or to dorsal corner of 1st gillopening (paratype). Spine of first dorsal fin (damaged in holotype; perfect in paratype) very much lower than horny part of the fin. Spine of second dorsal fin slightly curved, with a groove near anterior margin and another near posterior margin on either side as in the spine of first dorsal fin, much higher than spine of first dorsal fin, and considerably lower than horny part of second dorsal fin; base of former spine in advance of rear ends of pelvic fins. Caudal fin gently rounded dorsally, concave posteriorly on ventral lobe, and notched at rear end of ventral lobe, thereafter being nearly straight. Pectoral fins placed low down, outer (or ventral) side being nearly flush with ventral side of body. Dorsal, pectoral and pelvic fins rather small in size.

Dentition
Teeth of both jaws similar in shape, erect, symmetrical, or nearly so, with 3-5 cusps, the median cusp being the largest. Outermost row of jaw teeth and subsequent row very close to one another, forming nearly a single row and rendering the counting difficult. [3739]
