1995 Uvigerina asperula Czjzek — Ujiié, p. 63, pl. 6, fig. 8.

Remarks. Here we follow Ujiié (1990) in distin-

guishing species with well-developed hispid tuber-

cles from other hispid species such as Uvigerina auberiana d’Orbigny. The generic distinction between Euuvigerina and Uvigerina is based on the character of the inner structure of the apertural projection. This is occasionally difficult to observe in poorly preserved specimens.

Occurrence. Sporadic in the Yonahama Formation.
