Diarn. Page 



Fig. 1. Ccelodendrum furcatissimum, n. sp., . . x 50 1735 



A complete specimen with the central capsule and the big phseodium. 

 The spherical calymma envelops almost the entire skeleton. 



Fig. 2. Ccelodendrum furcatissimum, n. sp., . . x 300 1735 



A distal branch with its terminal ramification. 



Fig. 3. Ccelodendrum furcatissimum, n. sp., . x 100 1735 



One valve of the shell, with its galea and the four hollow forked tubes 

 arising from it. 



Fig. 4. Ccelodendrum furcatissimum, n. sp., . . . x 100 1735 



The central capsule with its nucleus ; on the left side one valve of the 

 closely enveloping shell (seen in vertical section), and its galea 

 with the origin of the four tubes. 



Fig. 5. Ccelodendrum serratum, n. sp., . . . . x 400 1737 



A flabellate terminal branch. 



Fig. 6. Ccelodendrum jlabellatum, n. sp., . . . x 150 1737 



A flabellate terminal branch. 



Fig. 7. Ccelodendrum spinosissimum, n. sp., . . x 300 1735 



Forked distal end of a terminal branch. 



Fig. 8. Ccelodendrum cervicorne, n. sp., . x 150 1736 



One valve of the shell, with its galea and the four tubes arising from it. 

 A network of protoplasm connects the distal branches. 



Fig. 9. Ccelodrymus ancoratus, n. sp., . x 50 1738 



A complete specimen, with the central capsule and the enveloping phffl- 

 odium. The surface of the spherical calymma is covered by a dense 

 network, from which arise numerous, anchor-bearing, radial tubules. 



Fig. 10. Ccelodrymus ancoratus, n. sp., . x!50 1738 



A small piece of the superficial network of the skeleton, with the zigzag 

 radial tubules arising from it, each of which bears an anchor with 

 two recurved denticulate teeth on the distal end.
