Remarks.

This taxon has been synonymized with Sultana (Metorthalicus) yatesi (Pfeiffer, 1855) by Richardson (1993) without further comments. Breure and Ablett (2015) followed this opinion, but doubt remained. In the context of this study we prefer to treat Fulton’s taxon tentatively as a separate species as it seems to differ by the stouter shell, the more inflated last whorl, and the uniform colour pattern.
