In the Meinoires de la Societe d'Emnlation du Departement du Doubs, 1859, Prof. Etallon describes among the numerous fossil sponges of the " Scyphia-kalk," near St. Claude, in the Departement du Jura, a peculiar family named by him the " Diktyonocoelidise." The species in question are said to be dis- tinguished from all other fossil and recent forms, by a quite pecu- liar internal structure. This structure is the more interesting that it bears a close resemblance to that of the Ventriculites of the chalk, as described by Mr. Toulmin Smith. The structure alluded to, consists in the existence in the substance of the fossil sponge of anastomosing tubes or canals, which may be straight and toler- ably regularly disposed, or tortuous and irregular. These canals are found partially or completely filled with calc-spar or oxide of iron. The authors, however, are disposed to believe, and show very good reasons for their belief, that these canals in the fossil were not really such in the living sponge, but rather that they re- present an original horny skeleton, and consequently that the Diktyonocoelidiae of Prof. Etallon do not differ intrinsically from the horny sponges. And they apply the same arguments in oppo- sition to Mr. Toulmin Smith's notion that the Ventriculites belong to a class of animals more highly organized than the sponges.
