Nihonia australis explained

Nihonia australis, commonly named the Australian turrid, is a species of sea snail, a marine gastropod mollusk in the family Cochlespiridae.

The name Nihonia australis has often been attributed to Gmelin (1791:3542), as a result of a confusion between Murex australis Gmelin, 1791 [= ''Pelicaria vermis'' <small>(Martyn, 1784)</small>] and Pleurotoma australis Roissy, 1805 [= ''Nihonia australis'']

Description

The size of an adult shell varies between 70 mm and 95 mm. The elongate-fusiform shell is yellowish white, encircled by raised, corded orange-brown ribs, with several intermediate striae. The blunt protoconch contains 1½ -2 whorls. The teleoconch contains 9½ -10 whorls. The outer lip is broadly rounded above into the rather shallow sinus. The long, straight siphonal canal is unnotched.^{[1] [2]}
