Odostomia derivata Wood, 1879: 39 , unnumbered text-fig. p. 40.

Menestho derivata – Harmer 1920: 583, p. 583, pl. 50, fig. 4.

MATERIAL AND DIMENSIONS. — Maximum height 1.6 mm, width 0.8 mm. — RGM.1365207 (1), leg. AWJ .

SPECIES CHARACTERISATION. — Shell fusiform. Protoconch type C. Teleoconch of 3.5 convex whorls separated by narrowly impressed suture. Sculpture consist of numerous spiral cords, broader than their interspaces, six on first teleoconch whorl, 18 on last whorl. Last whorl 70% of the total height. Aperture pyriform; outer lip not complete; columella without fold.

DISTRIBUTION. — Lower Pleistocene: NSB, England ( Wood 1879; Harmer 1920); Atlantic, Selsoif, NW France (this paper).

REMARKS We tentatively ascribe the specimen to Menestho derivata ( Wood, 1879) , described from the Lower Pleistocene Bramerton Crag (= Norwich Crag) of England. It is similar in sculpture to two extant northern European species: Menestho albula (Fabricius, 1780) and M. truncatula Odhner, 1915 , but both of these species are squatter with more convex whorls.
