A record of Solecurtus scopula (Turton, 1822) (Mollusca: Bivalvia: Solecurtidae) from the Strait of Dover, pp. 1-3, plates I-V, by Frank Nolf.

The presence of Solecurtus scopula (Turton, 1822) in waters near the North Sea is confirmed by the record of a single live-caught specimen trawled off Boulogne-sur-Mer, NE France.

Keywords: BIVALVIA, SOLECURTIDAE, Solecurtus scopula, Strait of Dover.

Thais lacera (Born, 1778) (Mollusca: Gastropoda: Muricoidae: Muricidae): an early record of an exotic species from the western Mediterranean Sea, pp. 9-11, plates I-IV, by F. Nolf.

Thais lacera is recorded and described from Ibiza. The shell was live trawled by Spanish fishermen in 1960, which means some decades before most of the other reports from the eastern Mediterranean Sea. As a result of our investigations we conclude that this Indo-Western Pacific species can be found throughout the whole Mediterranean Sea.

Keywords: Thais lacera, range extension, western Mediterranean Sea.

Neopycnodonte cochlear (Poli, 1795) (Mollusca: Bivalvia: Gryphaeidae) on the East Atlantic and Belgian coasts, pp. 16-18, plates I-XI, by F. Nolf.

A few juvenile specimens of Neopycnodonte cochlear (Poli, 1795) were found in Koksijde (Belgium) on 23 January 2005. This record in North Sea waters was confirmed by the find of more specimens in the harbour of Roscoff (Brittany, France) and of a sample in Galicia (North Spain).

Keywords: Neopycnodonte cochlear, GRYPHAEIDAE, Koksijde, Roscoff, Galicia.

Range extension for Lepidochitona canariensis (Thiele, 1909) (Mollusca: Polyplacophora: Tonicellidae), pp. 30-31, plate I, by B. Anseeuw & J. Verstraeten.

Lepidochitona canariensis (Thiele, 1909) is reported to have been found in Mauritania. This is a southern range extension for a chiton until now only known from the Canary Islands, Madeira, a few localities west of the Strait of Gibraltar and one report from the Mediterranean (south of the Iberian Peninsula).
