Shell, small, elongate, cylindrical, covered in life by a thin light brown epidermis. Surface sculptured with well marked curving growth lines crossed by fine subobsolete, sparse spiral lirations. The body whorl is drawn into a rounded apex posteriorly, the outer lip developing from the apex and completely hiding the spire. Outer lip thin, straight, rather retracted medially, cut away suddenly below, anterior margin truncated rather squarely. Aperture elongate, narrow above, narrower still and subparallel medianly, rather open below. Inner lip thin, spread over the parietal wall as a thin glaze. Columella concave, bearing a low fold. Height. 7,9 mm.; diameter. 3,1 mm.

This new species is very like Kaitoa scaphandroides Powell from South Georgia in general appearance but that species is much larger and lacks the columella fold and the relationship is probably not very close. Kaitoa scaphandroides has the apex hidden beneath a deposit of callus so that the apical characters cannot be determined. Volvulella truncata is very close to V.rostrata differing mainly in the very different anterior outline resulting from the anterior truncation and the less regular, more diffuse spiral sculpture. In addition the junction of the spire and outer lip is considerably more obliquely set.
