Gatliffena fenestrata (Tate & May, 1900) Description: Protoconch tall and prominent. Teleoconch elongate, of 5½ whorls, spire slightly convex in outline, whorls rounded, aperture ¼ of shell length; shell angled at base. Sculptured with about 17 axial ribs, fading out at base, crossed by about 5 spiral cords, forming beads at intersections. Six spiral cords on base. Outer lip straight in profile, with no posterior sinus; slightly expanded, slightly thickened internally, smooth or with 3 elongate denticles. Columella callus smooth. Anterior canal moderately long (broken off in Fig. 1), slightly upturned, forming a contraction in outer lip. Colour white. Size: Up to 9 mm in length. Distribution: Recorded from NSW, Victoria, SA and Tasmania. Habitat: Subtidal, 73-200 m, plus one beach record. Rare. Comparison: See Exomilopsis spica. Remarks: There are only five specimens of this species in the Australian Museum collection, the only NSW record being from 30 km east of Little Bay, Sydney, in 192-203 m. It probably belongs in the genus Exomilopsis. Fig. 1: 30 km east of Little Bay, NSW, 192-203 m. The anterior end is broken. (C.373481) |
