All SEM pictures taken from the Iles Kerguelen type population (sample BW424). Fig. 23. External scanning electron microscopy image of an entire valve showing the smooth, flat central area, the central fultoportulae, the undulating marginal structure, the marginal spines and the marginal fultoportulae. The arrows indicate the marginal depressions, split in several small, rounded pores. Figs 24–26. External views of several valves showing a variable number of central fultoportulae, the variability within the marginal spines and the clearly smooth central area. Fig. 27. Internal SEM image of an entire valve showing the smooth, flat central area, the marginal fultoportulae located on each costa, the rimoportula and the central marginal fultoportulae. The arrows indicate unbroken spines. Fig. 28. SEM external detail of the marginal part of a valve showing clearly the spines, the openings of the marginal fultoportulae (double-headed arrows) and the hyaline furrows between the raised striae (arrows). Fig. 29. Internal SEM detail of the rimoportulae and several costae bearing marginal fultoportulae. Note also the very finely areolated striae between the costae. Scale bar represents, 5 μm for figs 24–26 and 1 μm for figs 23, 27–29.
