Figs 13, 25F

Material examined: SOUTH AFRICA: KwaZulu-Natal: 1 lv, Kosi Bay, main reef, 1–4 km S of estuary mouth, stone surfaces, ± - 15 m, dived D. Herbert, 4.v.1990 (NMSA S2869) .

Description:Tube evenly arched, colourless, semitransparent. Surface crossed by coarse growth lines, assuming the form of small, hardly visible rings toward the aperture. The tube widens before the aperture, forming a ring-like swelling, which is crossed by some ill­defined annulations, after which it contracts again, ending with a very small ring. Microsculpture composed by a fine worm­like striation. Septum dome­shaped, protruding, with a low dorsal mucro. Periostracum colourless. Operculum thin, flat, corneous, multispiral, internal side with a slightly raised nucleus sorrounded by a tight spire of 7 whorls, external side with a concave nucleus. Length: 1.9 mm.

Distribution: Caecum gulosum is found in the eastern Pacific Ocean (Pizzini et al. 2013). A single specimen tentatively attributed to this species was found on the eastern coast of South Africa (Fig. 13).The presence of Caecum gulosum in South Africa needs confirmation.
