Inflatella (?) sp. Occurrence. Bav of Naples, unnamed shoal south of Pozzuoli, east of Ischia, depth 120 m, mud, dredge', 4 September 1969. , Description. (Fig. 63) The two specimens were growing on pebbles and consisted of small, erect, partly branching tubular pro- cesses, measuring about 5-10 x 1 mm. The colour was buff. The ma- terial has been entirely used for spicule preparations. Spicules. 1) Strongyles irregularly curved or flexuous, measuring 220-260 X am. 2) Tylotes measuring 150-170 x 6-7 , heads about fjim. Remarks. The allocation of this sponge is tentative, partlv owing to the inadequacy of the available material, partly because its peculiar spiculation gives no indication of near relatives. It is pro- visionally placed in the Coelosphaeridae - a very heterogeneous family - in the genus Inflatella, itself rather artificial. 100 pm. F"ig. 63 - Spicules of lììfljtelltì ? sp.
