. Annali del Museo civico di storia naturale Giacomo Doria. Natural history. SPONGES FROM EAST AFRICA 323. Fig. 60 - Pellina cavernosa sp. n., the holotype. Scale: 2 cm. Tabulocalyx pedunculatus , (Fig. 61, 62) Occurrence: North Kenya Banks (02°'S - 41°00'E), depth 110 m, dredge, 11 August 1971. Holotype: MSNG 48327. The body of the sponge is globose, cm in diameter; it is supported by a stalk cm thick, 6 cm long. The oscules are numerous, 3 to 5 mm wide, on crateriform elevations. The ectosome is a smooth crust made by oxeas in confusion, tangentially arranged in a single layer. Occasionally they form uncertan tracts. This crust is not easily separable from an underlying network of multispicular fibres 230-280 | thick, forming meshes 360-450 | wide. This network, apparent to the naked eye, is uniform, strictly two-dimensional. Below it, the skeleton is a dense mass of oxeas without orientation, traversed by two or three reticulations like the one mentioned above, a couple of millimeters apart, more or less parallel to the surface. Still deeper in the body, the skeleton consists of the dense mass of oxeas in confusion.
