The skeleton consists of a network of spiculo-fibres 16-34 [im thick, the main ones directed toward the surface, about 250 [ltcv apart. The meshes are very irregular, 100-500 [xm wide.

About half of them are markedly centrotylote. Remarks. The main character distinguishing this species from Ulosa stuposa is the centrotylotysm of a large part of its styles. Other differentiating features are slight. In U. tenellula the skeletal frame is somewhat weaker, the spiculo-fibres being thinner, with scarcer spongin and with spicules less regularly aligned. The surface ends of the fibres are more closely set. Ulosa t u b u 1 a t a sp. n. Occurrence. Off Calvi, depth 155 m, detrital, trawl, 18 July 1975. Holotype. msng 47177. Description. (Figg. 61, 61bis) The sponge appears to result from the coalescing of two individuals, as evidenced by the pre- 50 \xm.
