Original Description
E familia Halicalyptrinorum. Charateres Haliphormidis, sed sphaerae cavae pariete continuo regulariter cellulose et apertura simplice coarctata regulari instructo.

Cenosphaerae Pylosphaeris habitu proximae sunt, sed aperturam insignem non offerunt. Haliphormides Dictyospyridibus affines, sed solitariae nec geminatae sunt et aperturam irregularem nec simplicem gerunt. Acanthosphaerae sunt Cenosphaerae radiatim aculeatae.

Cenosphaerae et Acanthosphaerae cum sine apertura bene discreta existant et sphaeras reticulatas siliceas clausas referant, a Polycystinis reliquis aberrant, forsan ad Spongiarum carpella pertinent, Inclusos crystallos nunquam vidi.


Translation: Of the family Halicalyptrinae. With the characters of Haliphormis, but the hollow spheres have a continuous, regularly porous wall and are provided with a regular, simply contracted aperture.

Cenosphaera resembles Pylosphaera, but does not have a distinctive aperture. Haliphormids are related to dictyospyrids, but are solitary and not paired, and have an aperture which is irregular, not simple. Acanthosphaerae are Cenosphaerae with radiating spines.

Cenosphaerae and Acanthosphaerae, when they have closed reticulate siliceous spheres without a well-defined aperture, differ from other polycystins, and perhaps belong to the ""carpella"" of the sponges. I have never seen included crystals. (Translated from Latin by E.M.R. and W.R.R.)]
