Bolivina sp. “A”

Fig. 4I

Description: Triangular appearance. Depressed sutures. Wall has small pores and larger pores along sutures.Aperture is terminal. Width = 80 µm, height = 150 µm, width:height = 0.53:1.

Material examined: A27398 , A27399 .

Distribution: Around South Africa, Sea Point.

Remarks: Bolivina sp. “A” lacks the coarse perforations found on B. “ fossa ”, which also has sutures that are initially indistinct, becoming distinct towards the final chambers, whereas Bolivina sp. “A” has sutures which are quite distinct. Bolivina sp. “A” also differs from B. pseudoplicata which has strong excavations and ornamentations especially near the midline. Bolivina sp. “A” has a similar triangular shape to B. compacta and the wall is coarsely perforate, however, the pores are much larger and less dense and the sutures are more distinct than in Bolivina sp. “A”.
