New investigations in the Pliocene deposits of Challans (Vendée) have allowed to collect more than 3000 marsupiate echinoids, remarkably preserved. So, apical systems, especially the marsupium of the breeding temnopleurids T. (V.) bigoti and C. bardini, have been described and figured for the first time with complete specimens. Two new marsupiate species have been described: Arbacina hugueti nov. sp., third marsupiate species of the genus Arbacina to be known in the Neogene of western France after A. emmae NÉRAUDEAU, 2003 from the Messinian of Brittany and A. pareyni ROMAN, 1983 from the Pliocene of Normandy; Tremaster romani, new species and genus of temnopleurid, characterised by an uncommon supra-ambital tuberculation, with excressences of the test surrounding scrobiculated tubercles. A third new marsupiate echinoid, Coptechinus sp. A, has been found too, but it is very difficult to know if it is a new species or a new morphotype of C. bardini.
