Abstract
Two species of salenioid echinoids, Salenia minima Agassiz and Desor, 1846 and Hyposalenia heliophora (Agassiz and Desor 1846) from the Danian strata in the Maastricht area, are described and discussed. Biometrical parameters are statistically treated and compared with those of some other salenioids. It is shown that both species are probably good index fossils for strata of Danian age.
