 krummede. Tal). I, Fig. 5.

 formige, dels cylinderformede, nogle aabenmundede, andre 

 lukkede for Enden. Sækkens Vægge har en Tykkelse af 

 omtrent 0,5 mm , og inde i en af dem fandtes en kornet 

 Masse, i hvilken der forekom spredte Kiselnaale. medens

No record. 



Thi' following animals, instead of having spicules 

 resembling the formula ac 2 , have spicules according to the 

 formula trac, or blunt at the one extremity and acuate at 

 the other extremity. They ought, therefore, perhaps, with 

 mostshow of reason, to he classified under another generic 

 designation than the preceeding ones, but, as amongst those 

 animals described by Oskar Schmidt under the designation 

 Beniera, there are found forms of spicules with blunted 

 points, as well as with acuate points, I have retained this 

 generic designation, also, for these animals. 



Reniera digitata, n. sp. 



A sponge having five lobate branches proceeding 

 from one common stem; rather soft and loose in its struc- 

 ture. It has spicules of the formula trac only: partly 

 straight, partly, in single curves, and partly, with a few 

 spicules having double curves (PI. I, fig. 5).

Occasionally, isolated individuals, occasionally, collec- 

 tions of them, upon thin plates. The isolated sponges are 

 oblong, partly, pyriform, and partly, cylindrical: a few are 

 open-mouthed, whilst others, again, are closed at the extrem-

 0.5""", and contained in one of the bags was found, agranular 

 mass, in which scattered siliceous spicules appeared, whilst 

 the others were empty. The walls are formed of parallel, 

 thickish spicular fasciculi, outside of which, transversal spic- 

 ular fasciculi are found, placed at somewhat regular inter- 

 vals from each other, but, otherwise, intersecting each other 

 at more or less acute angles. In the reticulation formed 

 by these spicules; perforations occur, which completely pene-
