Clavatula nathaliae (Mollusca: Gastropoda: Conoidea: Turridae) a new species from Gabon: an old mystery finally elucidated, pp.1-7, plates I-VII by Frank Nolf.
In recent literature confusion originated after J. Knudsen’s misidentification of some shells belonging to the ‘Atlantide’ Expedition material as Clavatula gabonensis. The real C. gabonensis Melvill, 1923 is illustrated here and a new species-name is introduced for a mollusc living from Ghana to Gabon. Comparison is made with the related Clavatula strebeli Knudsen, 1952.
Key words: GASTROPODA, TURRIDAE, Clavatula nathaliae, Clavatula gabonensis, Gabon, new species.
Recognition of two new Clavatula species (Mollusca: Gastropoda: Conoidea: Turridae) in a complex group from Gabon and North Angola, pp.15-19, plates I-X by Frank Nolf & Johan Verstraeten.
The species figured as Clavatula sp. by Bernard in ‘Coquillages du Gabon’ and later on wrongly mentioned in recent literature as ‘Clavatula mourei’ or Clavatula marginata is introduced as the new species Clavatula quinteni. It is compared with Clavatula xanteni, another new species from North Angola. These shells have a close affinity with each other, Clavatula quinteni living in Gabonese waters, and Clavatula xanteni is found off the mouth of the Congo-river and in North Angola.
Key words: GASTROPODA, TURRIDAE, Clavatula quinteni, Clavatula xanteni, West Africa, new species.
