Species Compactogerina stellapolaris Grigelis 1977



Discussion / Comments:
Boudagher-Fadel et al. (1997):
Remarks: The holotype figured by Grigelis (1977) is a specimen with a very compact test, in which the sutures are only very slightly depressed and the equatorial periphery is not lobulate. This morphology agrees with that of two metatypes illustrated here (Plate 2.7, Figs 1-3,7). The sutures of another topotypic specimen also illustrated on Plate 2.7 (Figs 4-6), however, are much more depressed and the equatorial periphery is more lobulate; if the specimens figured here are indeed all conspecific, then they give a view of the range of the variation which occurred in the species, but not enough specimens are available to us to be sure. The aperture possesses a narrow lip which partly covers the umbilicus (this lip appears to be broken away on Plate 2.7, Fig. 6).
