Contributions to the knowledge of the Triviidae: XXVI. New species from French Polynesia (Mollusca: Gastropoda), pp. 1-5, figs 1-4, pls 1-2, by Dirk Fehse and Jozef Grego.

The study of Triviidae from the Pacific and Indo-Pacific has continued since the most recent description of species from French Polynesia. In the meantime more than 50,000 specimens have been examined and identified by the senior author. Dredgings and dive collecting by Jean Letourneux and his team brought up several dozens of new shells. Among this material two new species were discovered which are described as Trivirostra leylae nov. sp. and Trivirostra matavai nov. sp.

Contributions to the knowledge of the Eratoidae. VIII. Eratoidae of Mozambique and Madagascar, pp. 10-17, figs 1-2, pls 1-4, by Dirk Fehse.

From a large collection of Eratoidae from Conduceia, Mozambique two new species are described: Eratoena rosadoi nov. sp. and Alaerato elizabethae nov. sp. The examination of a huge amount of dredging material of the MNHN has allowed for the description of a further deep water Alaerato from NW Madagascar, named as A. virginiae nov. sp.

An unusual locality for Lepidopleurus cajetanus (Poli, 1791) (Mollusca: Polyplacophora: Leptochitonidae), pp. 22-23, pls 24-27, by Bruno Anseeuw.

A specimen of Lepidopleurus cajetanus (Poli, 1791) was collected off Cherbourg (Normandy, France). This appears to be the most northern report of a chiton that has been known as a Mediterranean, Iberian and Canarian species till now.

Keywords: MOLLUSCA, POLYPLACOPHORA, LEPTOCHITONIDAE, Lepidopleurus cajetanus, range extension.

An unusual habitat and colour form of Tectura virginea (O.F. Müller, 1776) (Mollusca: Gastropoda: Lottiidae), pp. 28-30, pls 31-32, by Arne Ghys and Frank Nolf.

After more than forty years of intensive observation on the coast of Normandy and Brittany in France a greenish and slightly orange coloured reticulated specimen has been found at Green Island, (Jersey, Channel Islands) for the first time. This unusual colour may be caused by the different habitat on algae instead of the underside of stones and valves of empty shells.

Keywords:Tecturia virginea, unusal colour, different habitat, diet.
