| Thanks to this psychological study, stretched over a period of four years (1968-1972) on the algae population of the Le Dramont rocky coasts, we had the possibility to distinguish 19 different groups. Their apportionment and floristic composition have been consciously observed and studied, in summer as well as during spring, and this up to a depth of 45 m. A high number (35) of sections were done for that purpose, all over the work territory. Some of them are reproduced here (fig. 1, 2, 3, 4), with an indication of the placement of the different groups. Next, we compared our results with those of previous works, and we were able to conclude that the studied area is very analogue to the one of the J. Feldman study of the Albères Coast. |

| Five spp of Echeneididae are presently known in the Mediterranean: Echeneis naucrates L., Remora remora (L.), R. brachyptera (Lowe), R. australis (Benn) and Rhombochirus osteochir (Cuv). All of them may now be reported from the area comprising the Ligurian and the Tyrrhenian seas. Many mistakes occurred in the past, chiefly concerning R. remora a name too often wrongly applied to different spp. Echeneis holbrooki from the gulf of Genoa is really E. naucrates. Only 2 specimens of R. brachyptera were found, both in Sicilian waters. R. australis is here recorded from the Tyrrhenian sea. Rh. osteochir has been hitherto overlooked, but probably is the commonest Echeneid in the Mediterranean. A list is given of specimens from several localities (Gulf of Genoa,... |

| Possible evolutionary trends within Polycystididae have been indicated by Karling (1956) while studying the male genital organs of seyeral turbellarian groups. For the moment his ideas seem the most valuable basis for establishing an intrafamiliar system of Polycystididae, and have hence been applied formally (Schockaert, 1974). However, it can be demonstrated with several examples that the underlying principles prove to be unsatisfactory when one tries to apply Hennig's methodology:-the subfamily Duplacrorhynchinae Schockaert & Karling, 1970, can be recognized as containing the most plesimorph polycystidids; a synapomorph character that would give us an indication of the monophyly of this taxon is lacking;-the homology of some glandular elements (al!... |
