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.
