World Polychaeta Database (WPolyD). Blake 1996 p.62 points out Laubier & Ramos is dated 1973, but printed 30 March 1974. Likewise Katzmann & Laubier (1975) dated the work as 1974. Note also that the pagination in the Archimer pdf reprint is incorrect
The study of various collections of Polychaeta Paraonidae from the Mediterranean (continental shelf, continental slope and abyssal plain) has shown a great interest. Seven species and three subspecies are new to science. One species related to a deep-Atlantic previously described species, is new to the Mediterranean. Some morphological comparative studies are carried out for species not existing in the Mediterranean. The 28 species or subspecies reviewed in this work are generally located in the western Mediterranean. Regarding the repartition with depth, four species are strictly located in the abyssal plain, while three others are widely distributed from the first tens of meters to the largest depths. Most of remaining species inhabit the continental shelf or the beginning of the slope; few of them have within this field definite ecological requirements, particularly in the infralittoral zone.
