Turbonilla acicularis (A. Adams, 1855) Description: Shell large, elongate and slender, spire nearly straight sided, up to 13 whorls. Protoconch coiled (Type B), of about 2 whorls, set on teleoconch with axis inclined at about 100° to teleoconch axis. Teleoconch whorls sculptured with about 14 strong axial folds, on last whorl terminating level with top of aperture; no spiral sculpture. Aperture wide, columella without plaits. Shell colourless transparent, becoming opaque white with age. Size: Up to 13 mm in length. Distribution: Endemic to Australia: Broken Bay, NSW, southwards and around southern Australia, to SA, including Tas. Habitat: Associated with seagrass in sheltered bays and estuaries, shallow sublittoral. Less commonly found on the open coast. Synonymy: This species has been known as Turbonilla acicularis A. Adams, 1853. The name was not properly published in 1853 and was published again in 1855, so it takes that date. Figs. 1–3: Twofold Bay, NSW (C.341623).
