This work is devoted to the sindy of cirealittoraJ rocky bottoms
along the coast of Roussillon. Environmcmental conditions (weak
sedimentation taking place beyond this area, continuons motion
of the water, salinity and temperature little changeable ail over the
year) make the animal community extremely rich and diversified.
The autbor gives the list of the collected species. Very grest originality of Sponges fauna. which reaches a luxuriance never
observed in the Western Mediterranéc, is pointed out; this may
he related to the continuous stirring and regular motion of the
water. Study of Sponges epifauna and endofauoa has been made.
From a bionomica1 point of view, two facies are opposed one to
the otber, detrital to the West and coralligen to the East of those
rocky bottoms. These communities located in the circalittoral level
play the role of a transitory Area. Substratum of tbose concretions
is in ail respects similar to a "beach-rocks".
