Original Description

This form, of rather small size, presents a neck of medium length (one third of the total length), terminating in a fairly wide, straight opening, gradually widening upwards. The chamber is elongated and terminates in a thin, transparent copula. In some individuals, the external wall forms a kind of tunic that appears to envelop the entire chitinozoan, and is more or less separated from the copula.

Size:
Total length: 204 µm; Length of copula only: 60 µm; Width of chamber: 77 µm; Width of neck: 56 µm

Untranslated description
Cette forme d’assez petite taille présente un col de longueur moyenne (un tiers de la longueur) et termine par une ouverture assez large, rectiligne, s’évasant progressivement vers le haut. La panse est allongée et se termine par une copula transparente et mince. Chez certains individus, on observe la paroi externe formant une sorte de tunique semblant envelopper tout le Chitinozoaire, et plus ou moins séparée de la copula.
