Subfamily Rhabdammininae Brady, 1884

Marsipella Norman, 1878

Marsipella sp. “A”

Fig. 2A

Marsipella: Loeblich & Tappan 1988: 23 , pl. 15, fig. 2.

Description: Small elongated test. One long tubular chamber. Wall composed of large sand grains. Exterior coarse. May be open on both ends or one end may be closed by aggregation of sand grains. Slightly twisted at final chambers. No visible sutures. Width = 92.3 µm, height = 323.07 µm, width:height = 0.29:1.

Material examined: A27391.

Distribution: Cosmopolitan.Around South Africa recorded at Sea Point and Kommetjie.

Remarks: This genus is particularly difficult to classify. The species may be regarded as Marsipella aggregate. However, the size of the species described here is much larger than the type specimen described by Norman (1878). Not many of these specimens were found, therefore, it was difficult to make a conclusive classification.
