Description

This form is only differentiated from the type by the dark chestnutbrown colour of the flammules all over the whorls clearly showing through in the aperture. This characteristic is accentuated by the contrasting white colour of the background, making the central band on the body whorl more visible. The edge of the mouth is also provided with a cream-white band. On the other hand the parietal callus is not white, but light brown. Measurements: 21-27.5 mm. Habitat: in muddy sand, depth: 6 m (CFN); 10-13 m (Strebel); 18-20 m (Bozzetti). Geographic range: Lome, Togo (Strebel), Ouidah (Whydah), Benin (Strebel), Victoria, Bota (= Limbe), Cameroon (CFN). Remarks: This form has recently been described as a new species by L. Bozzetti (2015): Fusiturris kribiensis. After comparison with the figures we can immediately conclude there was no reason to recognise this form as a new species and certainly not to classify it into the genus Fusiturris which has an uncertain status in the family CLAVATULIDAE. Moreover, this is merely a form, not only restricted to Cameroon but also occurring in neighbouring waters (Togo, Benin) together with the nominal type. Therefore there is no reason to regard it as a subspecies.
