Original Description
Test sphéroïdal; loges en partie recouvrantes, quatre seulement apparentes à tous les âges; ouverture latérale, semi-lunaire. Alternance totale ou partielle, mais irrégulière, les faces opposées n'étant plus semblables; le plus souvent l'alternance ayant lieu sur trois axes distincts, détermine par la prépondérance de volume des loges successives et leur extension en recouvrement, une sorte de spirale obscure et peucaractérisée. Coquilles d'une texture vitreuse, très-translucide
