Ambulacral pore-pairs forming broad bands over much of the oral surface. Material STUDIED. BMNHEE4351-5,EE6131-33,MGB 37471, 37511,37542,37557. Occurrence. Maastrichtian, horizons 4, 5, 6 and 7/8, Santander. Lower Maastrichtian of the Homes Morts Member at Sapeira, Santa Engracia and Salas de Pallars, Tremp Basin (Gallemi, 1992). Maastrichtian, top of bed 1, Olazagutia Pass, Navarra. Maastrichtian of Mas de Santa Maria, near Ibi, Alicante province (Gallemi et al. 1995). The type comes from the Maastrichtian of Saint Proupiary, near Auzas, Haute-Garonne, France and it has also been recorded from numerous other localities in Haute-Garonne, including Ausseing Massif, Picou near Roquefort, Mont Saunes, Beauchalot, Saint- Martory and Salies (Lambert, 1907). Remarks. Differs from C. magnificus (d'Orbigny) in having a longitudinal rather than transverse periproct, and from C. douvillei (Cotteau & Gauthier) in having a small, almost circular peristome as opposed to the distinctly oblique and large peristome of that species. This species becomes most common between levels 6 and 8 in the Maastrichtian of Santander. i PLATE 3 Figs 1,2 Conulus gigas (Cotteau, 1856), BMNH EE4354, Maastrichtian of Santander, Cantabria.
