ITLIT/.KR-FINALI Pellina cavernosa (Fig. 59, 60) Occurrence: Mombasa, Port Tudor, depth 30-40 m, dredge, 21 February 1974. Holotype: MSNG 48326. The specimen is irregularly massive, with some now broken fistules. The consistency is brittle, the colour in life was light orange (). The structure of the choanosome is microcavernous. The ectosomal skeleton is made by tangentially arranged oxeas in loose irregular groups showing not more than a tendency to form a reticul- ation. The subdermal lacunae are 400-600 firn wide. The choanosomal skeleton consists of irregular tracts or loose sheafs of oxeas forming meshes 600-800 jo,m wide, with many spicules in confusion. The spicules are oxeas variable, measuring 245-390 x 16-23 firn, with frequent stylote or strongylote Fig. 59 - Spicules of Pellina cavernosa sp. n. Scale: 100 um. Tabulocalyx gen. n. Oceanapiidae. Ectosomal skeleton a crust made by a single tan- gential layer of oxeas in confusion, occasionally forming vague thin tracts. It is supported by a strong, two-dimensional network of plurispicular fibres. Below it the skeleton is a dense mass of oxeas in confusion, cut across by several two-dimensional networks like the one mentioned above, separate from each other, more or less parallel to the surface. Deeper into the body, the skeleton consists of the mass of oxeas in confusion, traversed without regularity by strong plurispicular fibres. Type species: Tabulocalyx pedimculatus sp.
