Species Blowiella duboisi Chevalier 1961


Discussion / Comments:
Banner & Desai (1988):
This species is characterised by its high chambers (as high as long) and by its exceptionally broad umbilicus (at least 25% of the greatest diameter). The chambers are higher than in any paratype of B. blowi and higher than in any specimen we would ascribe to that species.
