Xenuroturris incredula (Iredale, 1931) Description: Shell sculptured with plain spiral ribs, alternating large and small, not nodulose; 10-12 on penultimate whorl. Axial sculpture absent. Columella smooth, outer lip broken. Colour rich reddish brown. Size: 60 mm. Distribution: Type locality: Port Jackson, NSW, dredged. Remarks: This species is known only from one dead shell, dredged from Sydney Harbour by the dredge "Triton" in the 1920's. It is probably a fossil, as the "Triton" dredged far below the harbour bed. Wilson (1994, p. 196) considers this to be a specimen of Xenoroturris cingulifera (Lamarck, 1822). Fig. 1: HOLOTYPE Port Jackson, NSW, dredged (C.057756) |
