Excerpt from Recherches sur les Planariés Et les Némertiens de l'Amérique du Nord
Le vitellus qui, jusqu a ce moment - là, était resté homo gène dans sa structure, tend dès lors à se diversifier, pour constituer deux couches dissemblables et se transformer ainsi en Planuta. Celle-ci abandonne l'enveloppe ovariale vers le vingt - quatrième jour après la ponte, pour vivre en liberté en plein élément.
