Encentrum striatum Althaus, 1957

A single specimen of E. striatum was found in psammon from the Côte d’Azur at Îlot de la Fourmigue, 3.5 km off shore, depth 15 m, June, water temperature 16 °C. The species was originally described from psammon of the sea water aquarium at Varna, Black Sea, Bulgaria ( Althaus 1957), and reported from psammon of sandy beaches from the North Sea, island Sylt, Germany ( Tzschaschel 1979), and from hygropsammon of a saline backwater- pool in the Santa Rosa Sound, Gulf of Mexico, Florida, U.S.A. ( Turner 1990).

The trophi need redescription as SEM ( Fig. 27 D) shows a more complicated morphology with differences in number of apical rami teeth and preuncinal teeth, and shape of intramallei and supramanubria, that could not be observed by light microscopy ( Althaus 1957; Tzschaschel 1979). Such a redescription awaits discovery of additional specimens.
