Neritidae – Neritinae: Nerita (Lisanerita) melanotragus E. A. Smith, 1884 (‘eastern black nerite’)

Synonym(s): melanotragus E. A. Smith, 1884.
Typical shell-length 25 mm. Shell generally indistinguishable from that of N. atramentosa, but the strongly brown-tinged operculum of the living animal is characteristic. Lives intertidally on rocks. Native. Occurs in eastern Australia (QLD, NSW, TAS and VIC); also New Zealand. In Tasmanian waters, this species is usually the dominant Nerita around Flinders Island and in the E, but rare or absent from the N, S and W coasts.
