Diam. Page 



Fig. 1. Coelodendrumfurcatissimum, n. sp., . . x 50 1735 



A complete specimen ■with the central capsule and the big phaeodium. 

 The spherical calymma envelops almost the entire skeleton. 



Fig. 2. Coelodendrumfurcatissimum, n. sp., . . x 300 1735 



A distal branch with its terminal ramification. 



Fig. 3. Ocelodendrum 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. Coelodendrumfurcatissimum, 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. Coelodendrum serratum, n. sp., . . . x 400 1737 



A flabellate terminal branch. 



Fig. 6. Coelodendrum fahellatum, n. sp., . . . x 150 1737 



A flabellate terminal branch. 



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



Forked distal end of a terminal branch. 



Fig. 8. Coelodendrum 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. Coelodrymus ancoratus, n. sp., . . . x 50 1738 



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

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

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



Fig. 10. Coelodrymus ancoratus, n. sp., . . . x 150 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.
