Biology Type of larval development: long lasting planktotrophic (teleplanic), inferred from multispiral protoconch. [details]
Diagnosis Shell up to 80 mm, with a moderately high spire and a strongly distorted profile. Protoconch large (2 mm), globose, distinctly cyrtoconoid with three smooth whorls. Teleoconch of 7-8 whorls, the body whorl compressed on the side of the aperture and increasingly inflated opposite to it. Sculpture of low spiral cords, and of narrow axial ribs which form indistinct nodes where crossing the spirals; interspaces between cords furnished with a small intervening cordlet. Varixes situated at about each 3/4 of a whorl over the last whorls. Aperture subtriangular, considerably constricted by outgrowths of the outer lip and of the columellar edge; outer lip provided with 6-7 elongate denticles of which the third (from adapical side) is markedly larger; parietal edge with a broad, thin and shiny callus, continued to form a broad shield also bordering the columella; provided with small blunt tubercles and molded over the varix of preceding whorl but never bearing a distinct plait or denticle on the adapical side; columellar edge forming a thick outgrowth which extends over the aperture, provided with denticles which increase in size towards the adapical side. Siphonal canal short. Periostracum hairy, rather short over most of the surface, with longer bristles over the varices. Colour whitish to tan, the aperture tinged with brown on the edge of the outer lip and on the parietal/columellar shield.
This species is distinguished from the West African Distorsio smithi (von Maltzan, 1887) in being smaller, with a more attenuated sculpture.
