This is proposed for the Rissoa rosea Hutton, 1873, which is invalidated by Rissoa rosea Deshayes, Île Réunion Moll., p. 61, pl. vii, fig. 29, 1862. The reference to the genus Estea is tentative, as the specimens before me, identified from their coloration as Hutton's species, incline rather to Amphithalamus, and might be better grouped there. I suggest that more than one species is classed under Rissoa rosea Hutton through the prejudice of the coloration.”
