Original Description
Polycystinum compositum e Calodictyis. Testula silicea plana spongioso-cellulosa, lobato-stellata. Cellulae disci spongiaceae concentricae. Membrana cellulosa radios ad apices usque coniungens.

Ab affini Histiastro fossili Antillarum membrana totos radios involvente differt, quae in illo prope discum solummodo observatur. Praeterea aculei validi Histiastri triactidis et quaternarii radios terminant, quae in Euchitonia desiderantur.

Translation: Composite polycystin of the Calodictya. Small test, siliceous, flat, spongy-porous, lobate-stellate. Pores of the spongy disc concentric. A porous membrane connects the radii all the way to their apices.

Differs from the related fossil Histiastrum from the Antilles, which has a membrane only near the disc, in having a membrane surrounding all the radii. Besides, the radii of Histiastrum triactis and H. quaternaria terminate in strong spines, which are lacking in Euchitonia. (Translated from Latin by E.M.R. and W.R.R.)]

Etymology: From the Greek euchitonia = nice shell"
