Cingulina brazieri Angas, 1877 Description: Shell large, elongate and slender, spire weakly convex in outline, up to about 12 whorls. Protoconch (Type B) coiled, about 1¾ whorls, set on teleoconch with axis inclined at about 110° to teleoconch axis. Teleoconch whorls straight-sided, sculptured with 3 strong spiral cords, sometimes with weak and irregular axial threads between; suture deeply indented. Aperture elongate, length greater than width; no plaits on columella.. Colour opaque white. Size: Up to 12.5 mm in length. Distribution: Endemic to Australia: central Queensland, southward and around southern Australia to Geraldton, WA. This is common in NSW, but if the identification of specimens in the Australian Museum is correct, it is rare in Victoria and South Australia and does not occur in Tasmania. Habitat: In NSW, known from beach washup and down to 66 m. Common. Comparison: Compared with Cingulina spina, the spiral cords are flatter with wider separating grooves, and the aperture is longer. Synonymy: Laseron (1951) used the name Cingulina circinata A. Adams, 1860 for this species, but that was a misidentification. Fig. 1: Bradleys Head, Sydney Harbour (C.341362). |
