Original description: Diagnose: variété caractérisée par le nombre moins élevé des loges (6-7), qui augmentent régulièrement et rapidement de taille dans le dernier tour, donnant au test un enroulement d'aspect evolute.

Description: par rapport à la description générale de l'espèce, il y a lieu de noter les particularités suivantes. Dernier tour de 6,5 loges environ, celles-ci augmentant rapidement de taille, le dernier tour montrant ainsi une tendance au déroulement. Face terminale plus haute que large. Ombilic de petite taille. Enroulement apparemment sans dominance (50/50).
