Extra details from original publication
Remarks: Protentella may be differentiated from other hastigerinids and globigerinids by its planispiral test with radially elongate chambers in the later stages, and by the smooth wall texture. A few specimens have slight knobs on the chambers which may represent the bases of large spines, although because of their rare occurrence their significance could not be determined.
