"Dimensions. - ½ millim. Coquille globuleuse, spherique, reguliere, tres mince, assez rugueuse, couverte partout de tres petits trous. Ouverture arrondie. Couleur blanc jaunatre. Extra details from original publication "Observations. - Il serait possible que, dans certaines circonstances, I 'animal put fermer l'ouverture de la coquille; du moins, celle-ci n'est-elle pas toujours visible, et n'est-elle ouverte que sur un sixieme des individus tres frais. Nous avons longtemps balance avant de placer ce singulier petit corps parmi les Foraminiferes; aussi n'en avons-nous pas parle dans notre tableau methodique, quoique nous le connussions; mais, depuis que M. Dujardin a observe son Gromia, il nous est reste d'autant moins de doute a son regard, que les Globigerines nous offrent de petites spheres semblables, formant leur spire. Cette coquille a d'ailleurs la contexture du test de ce dernier genre; seulement elle n'est composee que d 'une seule loge, et reste a l'etat parfait dans les memes conditions de forme que nous trouvons pour base des differents modes d'accroissement que nous voyons dans les autres .
"Il est probable que l'animal peut faire sortir un faisceau de filaments non seulement par l'ouverture de la coquille, mais encore par les nombreuses petites ouvertures de sa surface."
