Description

Figure 9. Ebiscothyris bellonensis gen. et sp. nov., cruise EBISCO, Coral Sea, South-West Pacific, SEM micrographs; A, B, ventral valve, station CP 2556, 741–791 m depth, IB-2013-7; A, transverse section of the entire shell showing the primary layer (pri) underlain by the fibrous secondary layer (sec), passing into the prismatic tertiary layer (ter); B, section of the shell showing primary (pri), secondary (sec), and tertiary (ter) layers; a puncta with a radiating brush is also visible; C, D, dorsal valve, CP 2557, 800–923 m depth, IB-2013-5; C, latero-oblique view of internal surface, showing the incurved valve margin built of densely arranged sheets of secondary fibres (left) and prisms of tertiary layer (right); D, internal surface showing discrete units of prisms and very small punctae (arrows). E, F, Kanakythyris pachyrhynchos Laurin, 1997, cruise NORFOLK 2, Norfolk Ridge, station DW 2136, 402–410 m depth; E, transverse section of the entire shell; F, internal surface with discrete units of prisms. Scale bars: A, C, D, E, F, 50 μm, B, 20 μm.
