Species Blowiella maridalensis Bolli 1959

Discussion / Comments:

Banner & Desai (1988):
We follow Bolli (1959) in distinguishing this species by its consistently depressed, reniform chambers. which are distinctly longer than they are high. Like B. blowi, it possesses a broad umbilicus, but the two species seem consistently to be separable on their chamber shapes.
Boudagher-Fadel et al. (1997):
Remarks: This species is distinguished by its reniform chambers, which are distinctly longer than high, and its broad umbilicus.
