Remarks.

The type locality mentioned by Sowerby could not been found in modern gazetteers. Since he was a shell dealer and obtained his specimens through third persons, there might have been a mistake in labeling. In case this assumption is correct, the province of Santiago de Chuco might have been meant; this province is located west of and adjacent to the Marañon river. This species was regarded so far as Orthalicus macandrewi , but is unlike other Orthalicus species in shell shape and colouration. It is now tentatively placed in Sultana (Metorthalicus) , but future studies are needed to confirm this.
