CORYPHELLA NOBILIS VERRILL, 1880

( FIGS 13 , 15A–D , 16A, B )

Diagnosis: Body wide, with continuous notal ridge. Rhinophores wrinkled, orange to light pink with white pigment on top. Cerata in continuous rows, long, colour from beige to pink, reddish-orange and bright orange. Jaws triangle plates, masticatory process with 9–12 rows of strong conical denticles. Radula triserial. Rachidian tooth triangle plate of different proportions with non-compressed or slightly compressed conical cusp and seven to nine denticles on each side. Lateral teeth triangle, bearing 10–15 small denticles, with attenuated basal process. Vas deferens slightly curved, widened. Penis lobe-shaped.
