Extra details from original publication
RAPPORTS ET DIFFÉRENCES : Cette espèce se distingue aisément des précédentes par ses loges adultes non globuleuses, son côté spiral pustuleux au-dessus des premiers tours de spire et par ses carènes, parallèles à la périphérie et dans le prolongement les unes des autres. Elle se rapproche également de la mutation de Rosalina Linnei à loges « coniques» de J. DE LAPPARENT (1) par sa forme générale et ses loges à plancher très relevé, mais s'en distingue par un bandeau périphérique net et non réduit à une simple carène.
