Amphilonche lanceolata, n. sp., 



Amphilonche hydrotomica, n. sp., 



The spindle-shaped central capsule is filled up with small granules. The 

 clear calymma forms conical sheaths for the spines, with myophriscs. 



Amphilonche diodon, n. sp., . 



Amphilonche concreta, n. sp., 



A complete specimen with the cylindrical central capsule. 

 Fig. 4a. Central part of the skeleton, 



Amphilonche violina, n. sp., . 



Amphilonche conica, n. sp., . 



The ellipsoidal central capsule contains numerous nuclei and is enclosed 

 by the calymma. The conical sheaths of the latter include the radial 

 spines completely and exhibit coronets of myophriscs. 



Acantholonche amphipolaris, n. sp., . 

 Acantholonche peripolaris, n. sp., . 

 Amphibelone pyramidata, n. sp., 



Amphibelone cultellata, n. sp., 



The central capsule contains numerous spherical nuclei and is enclosed by 

 the hyaline calymma, which forms conical sheaths around the spines.
