Diagnosis
ReferenceDiagnosis
A. Williams 1962Transversely, or less commonly elongately, subpentagonal Triplesia, about four-fifths as long as wide in intermediate stages of growth with a short hinge-line less than one-third the maximum width of the shell; brachial valve strongly trilobed with inflated lateral areas and a rounded, or more commonly subcarinate, median fold originating at about 3 mm. from the umbo; pedicle valve reduced in area, with a strongly geniculate median tongue directed dorsally, beak erect, shell surface apparently smooth but commonly ornamented antero-laterally by fine costellae, about 4 per millimetre, arising by intercalation and best seen on exfoliated specimens; teeth massive, dental lamellae strong, subparallel; sockets slightly curved and parallel with the hinge-line, brachiophores short, rod-like.
