Scale bar = 1mm. tent, the two forms are simply treated as varieties of the same species here. The species described here appears identical to the speci- men described from the Maastrichtian of Madagascar by SMITH Cottreau (1908) under the name Phymosoma archiaci Cot- teau var. It differs from true P. archiaci in having a broader, more granular interradial zone, and in having less well- developed secondary tubercles on interambulacral plates. The species P. hexoaporum was established by Lambert (1927) for specimens from the Maastrichtian of Sopeira, province of Aragon, Spain. P. hexoaporum differed from all other species of Phymosoma described previously in having compound plates composed of six elements at the ambitus rather than five. Later, Checchia-Rispoli (1933) described the same species from the Maastrichtian of Libya under the name P. paronai Checchia-Rispoli. This too has six or seven elements in ambital ambulacral compound plates.
