Diagnosis
ReferenceDiagnosis
G. Breton 1992Marginals wider than long and high. External face highly convex to angular. Lateral faces slightly concave, with few scattered pits and a slight sickened external margin. Internal face highly concave, separated from the face of articulation with abactinals (or actinolaterals) by a strong transverse ridge. Intermarginal face frequently divided in two or three faces, which suggest alternating marginals and potential intermarginal plates. Ornament of fine dense granule-pits, slightly projecting in the middle of the external face.
