1994 Pseudoclavulina serventyi (Chapman and Parr) — Jones, p. 53, pl. 48, figs. 14—16; Loeblich and Tappan, pp. 32, 33, pl. 45, figs. 12—19.

Remarks. LeRoy (1941, part 1) compared this species with Pseudoclavulina anglica Cushman (1936) which was originally described from the Eocene. Pseudoclavulina anglica closely resembles P. serventyi , and could turn out to be synonymous if the stratigraphic range of the species can be confirmed to be continuous.

Occurrence. Four specimens from the Oura Formation, a single specimen from the Onogoshi Formation.

FIGURE 7. Family Textulariidae, Pseudogaudryinidae, and Valvulinidae. All scale bars = 0.1mm, unless otherwise indicated. 1, 2. Bigenerina nodosaria d'Orbigny, 1: MPC-26035 from sample 2 (Minebari Formation, PF5); 2: MPC- 26036 from sample 11 (Onogoshi F.,?PF1). Difference of coarseness and test size between specimens of figured 1 and 2 probably reflect eco-phenotypic variation and preservation. 3, 4.
