Thuridilla lineolata

Thuridilla lineolata was described in 1905 by Rudolf Bergh from specimens collected in Indonesia. It was found again in Indonesia by Pauline Fiene-Severns 90 years later. The specimen shown here is one of several recently found in Cebu, Philippines, where this species appears to be fairly common. Also collected in the same area were Thuridilla bayeri and T. kathae. The genus was recently reviewed in the Proceedings of the California Academy of Sciences (1995) which included the descriptions of nine new species.
