Originally Petit de la Saussaye (1851) described a shell from West Africa as Fusus albocinctus comparing it with Pusionella vulpina (Born, 1780). Later on, Tryon (1884) regarded this shell as a variety of the latter, an opinion followed by Tucker (2004). However, this shell is not P. vulpina at all but merely a form of Pusionella nifat (Bruguière, 1792), differing from its usual appearance by the dark brown colour and median white band on the body whorl. Although this form is typical of specimens living on the Islands of São Tomé & Principe, it is probably not a subspecies as it has also been recorded from Senegal.

Confirmation of the presence of Fusinus rostratus (Olivi, 1792) as a new invader in northern waters of Brittany (France), pp. 9-16, plates I-IV by F. Nolf.
Several specimens of Fusinus rostratus (Olivi, 1792) have been reported in northern Brittany as a non-indigenous invader in the past three years. Seven specimens of this predatory gastropod were found in the inner part of the Bay of Morlaix in October 2007. Three other specimens were already obtained by a Belgian marine biologist from the same area in August 2006. Most likely, this habitant of the Mediterranean Sea, also recorded from Morocco, Portugal and Galicia, was introduced via oyster translocation.

On the presence of Coralliophila trigoi Mariottini, Smriglio & Rolán, 2005 (Mollusca: Gastropoda: Muricidae) in the southeastern Atlantic Ocean, pp. 17-27, plates I-VIII, by F. Nolf & J. Verstraeten.
A serious range extension is presented for Coralliophila trigoi Mariottini, Smriglio & Rolán, 2005, recently described as a new species from the northeastern Atlantic Ocean, more exactly from Galicia, Spain. The species was soon found to range from Galicia to Algarve, Portugal and from Almeria and Malaga (Alboran Sea, Spain) into the Mediterranean Sea (Secche di Vada, Livorno and Sardinia, Italy). A number of specimens found in the Bellas Bay, Luanda, Angola completely match the samples from the northeastern Atlantic Ocean. Up to now, specimens from the Gulf of Guinea remain unknown.
