Fig. 1. Amphilonche lanceolata, n. sp., . . . . x 300 783 



Fig. 2. Amphilonche hydrotomica, n. sp., . . . . x 300 786 



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

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



Fig. 3. Amphilonche diodon, n. sp., . . . . . x 300 783 



Fig. 4. Amphilonche concreta, n. sp., . . . x 100 787 



A complete specimen with the cylindrical central capsule. 



Fig. 4a. Central part of the skeleton, . . . X 400 



Fig. 5. Amphilonche violina, n. sp., . . . . . x 300 787 



Fig. 6. Amphilonche conica, n. sp., . . . . . x 300 785 



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. 



Fig. 7. Acantholonche amphipolaris, n. sp., . . . . x 200 790 



Fig. 8. AcantJiolonche peripolans, n. sp., . . . x 300 791 



Fig. 9. Amphibelone pyramidata, n. sp., . . . x 300 789 



Fig. 10. Amphibelone cultellata, n. sp., . . . . x 400 789 



The central capsule contains numerous spherical nuclei and is enclosed by 

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



Fig. 11. Stauracantha johannis, n. sp., . . . x 400 763 



Basal part of a radial spine, exhibiting the peculiar torsion of the basal 

 leaf-cross and the central apex. 



Fig. 12. Astrolophus Solaris, n. sp., . . . . x 200 732 



Fig. 12a. A group of larger and smaller radial spines united in the centre. 



Fig. 12&. Three isolated spines (one larger and two smaller), . . x 200
