Type material. 29 spms., (MNHN 6844); 8 spms., (MNHN 6845); 10 spms., (MNHN 6846); 16 spms., (MNHN 6847); 14 spms., ( MNHN 6848 About MNHN ), all syntypes from Cape Horn Expedition.

Type locality. “ Terre de Feu ”; in 1889 the authors mentioned “ Baie Orange ”, Lapataia in 21 to 198 m depth [Tierra del Fuego].

Description. Shell small, around 10 mm in height, fusiform, of six flat whorls; protoconch of 2 1/2 flat or very weakly convex whorls, entirely smooth, transition to teleoconch weakly defined; suture impressed; aperture elliptic, usually with sharp lip, siphonal canal deep, short. Parietal callus very thin, well defined. Growth lines, faint, closely spaced over the entire shell. Shell color reddish, brownish, outside and inside.

Operculum ( Fig. 17 View FIGURE 17 E) shape elliptical, subterminal nucleus, attachment area surrounded by a thick rim.

Radula ( Figs 18 View FIGURE 18 A–C) with tricuspid, rectangular rachidian teeth, all cusps of the same size; base of rachidian slightly curved; lateral teeth Prosipho- like with the basal plate produced into a typical “handle” more than half the width of the tooth, with 3 cusps, innermost smaller, two externals curved, pointing towards the rachidian, outermost, simple and smaller.

Penis cylindrical, with a small papilla rising from a hole.

GoogleMaps

Distribution. Puerto San Julián, Santa Cruz to Ushuaia, Cape Horn, Tierra del Fuego and Staten Is.

Remarks: This species is hard to find, perhaps because of its small size. It is similar to A. paessleri ; however, the shell is more slender and the aperture is smaller. A. cerealis lacks the distinctive spiral furrows at the base of the last whorl.
