PLATE 121.

Legion PHÆODARIA.

Order PHÆOCONCHIA.

Family Cœlodendrida.

PLATE 121. Cœlodendrida. Diam. Page. Fig. 1. Cœlodendrum furcatissimum, n. sp., × 50 [1735] A complete specimen with the central capsule and the big phæodium. The spherical calymma envelops almost the entire skeleton. Fig. 2. Cœlodendrum furcatissimum, n. sp., × 300 [1735] A distal branch with its terminal ramification. Fig. 3. Cœlodendrum furcatissimum, n. sp., × 100 [1735] One valve of the shell, with its galea and the four hollow forked tubes arising from it. Fig. 4. Cœlodendrum furcatissimum, n. sp., × 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. Cœlodendrum serratum, n. sp., × 400 [1737] A flabellate terminal branch. Fig. 6. Cœlodendrum flabellatum, n. sp., × 150 [1737] A flabellate terminal branch. Fig. 7. Cœlodendrum spinosissimum, n. sp., × 300 [1735] Forked distal end of a terminal branch. Fig. 8. Cœlodendrum cervicorne, n. sp., × 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. Cœlodrymus ancoratus, n. sp., × 50 [1738] A complete specimen, with the central capsule and the enveloping phæodium. The surface of the spherical calymma is covered by a dense network, from which arise numerous, anchor-bearing, radial tubules. Fig. 10. Cœlodrymus ancoratus, n. sp., × 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.
