About the surprising presence of Donax longissimus Thiele & Jaeckel, 1931 (Mollusca: Bivalvia: Donacidae) in Western Sahara: a comparison with similar E Atlantic and South African species, pp. 1-26, pls I-XVI, by Frank Nolf.
Specimens of an unknown Donax have recently been collected off La Sarga, Dakhla, Western Sahara, Morocco, a poorly explored area. Similar specimens were already known from South Africa. Thorough investigation has revealed that these shells belong to Donax longissimus Thiele & Jaeckel, 1931, a species often confused with Donax burnupi G.B. Sowerby III, 1894 also present in South Africa and Mozambique. In this paper Donax longissimus is compared with other similar species from the E Atlantic waters and D. prolongatus (Turton, 1932) is regarded as a junior synonyms.
Contributions to the knowledge of the Eratoidae. X. New species in the genus Proterato F.A. Schilder, 1925, pp. 27-31, pls I-II, by Dirk Fehse.
Recently discovered species from the Philippines and belonging to the genus Proterato F.A. Schilder, 1925 are described. The new species are briefly discussed and compared with similar species.
A dark-marginated form of Zonaria pyrum (Gmelin, 1791) (Mollusca: Gastropoda: Cypraeidae) from Lebanon: further evidence of a wrongly assumed subspecies, pp. 32-36, pls I-III, by Frank Nolf.
A specimen of a dark marginated Zonaria pyrum has been collected from the coast of Lebanon. Until now it has always been supposed that such a form was restricted to the south of the Iberian Peninsula. It was therefore regarded as a subspecies (Deprez & Govaert, 2009). The presence of a similar pattern from the eastern Mediterranean Sea excludes this supposition and downranks the subspecies Z. pyrum nigromarginata Deprez & Govaert, 2009 to the status of a mere form.
