Figures 5-6. Two optical sections through test cf.
Nebela. a=aperture; f=flange; p=plate. UCMP type 39886.
Figure 7. Test cf. Pontigulasia. UCMP type 39887.
Figures 8-10. Unidentified protists. n=nucleus with possible nucleolus; w=cell wall. In figure 10 the double
image is due to diffraction of light by the amber. Figure 8: UCMP type 39888; figure 9: UCMP type 39889; figure 10:
