Tripterocalpis ogmoptera, n. sp., × 300 [1138] Central capsule. In the centre the striate podoconus, above it four oil-globules, to the right the nucleus. Fig. 6. Tripocalpis triserrata, n. sp., × 600 [1136] Fig. 7. Tridictyopus conicus, n. sp., × 300 [1145] Fig. 8. Tridictyopus vatillum, n. sp., × 400 [1145] Fig. 9. Cyrtophormis spiralis, n. sp., × 400 [1166] Fig. 10. Archicorys ovata, n. sp., × 300 [1185] Fig. 11. Cyrtocalpis gromia, n. sp., × 400 [1188] Fig. 12. Archicorys microstoma, n. sp., × 400 [1185] Fig. 13. Cyrtocalpis urceolus, n. sp., × 500 [1186] The ovate central capsule exhibits in the lower half the podoconus, in the upper half the spherical nucleus and three oil-globules. Between the capsule and the shell numerous xanthellæ, partly protruded through the shell-mouth along the radiating pseudopodia.
