Dimensions (in mm): D, diameter; Wb, whorl breadth; Wh, whorl height; U, umbilical diameter. Whorl breadth and height are given for intercostal sections only. Figures in parentheses are dimensions as a percentage of the total diameter. Sutures: the terminology of Wedekind (1916), as revised by Wiedmann & Kullman (1981), is used. E, external lobe; L, lateral lobe; U, umbilical lobe; I, internal lobe. The terms 'inner' and 'outer ventrolateral tubercles' are used respectively for the Treatise (Arkell et al. 1957) terms 'lower' and 'upper ventrolateral tubercles'. Localities. Unless otherwise stated, the material described is from cuttings on the Calabar-Ikot Ekpene road, south-east Nigeria. Certain specimens cannot be assigned with certainty to an exact horizon. Those that can are localized according to their distances from Calabar using the mileposts as reference points.
