Radula

Radular formula approximately 118 × 60.1.60 (Op- 690) ( Fig. 19G), 120 × 70.1.70 (NSMT-Op R: 1140) ( Fig. 18M). Radular teeth slightly yellowish. Central tooth elongate with four to seven (more commonly five to six) distinct but adpressed smaller cusps ( Figs 18N, P, 19H, I). Inner lateral tooth hamate with relatively narrow base and long curved cusp; approximately three to seven outer denticles and one or two inner denticles ( Fig. 19H). Outer lateral teeth are elongated hook-shaped, bearing up to ten denticles ( Figs 18O, 19J).
