Abstract
    The MUSORSTOM Expedition has gathered stalked crinoids (family: Isocrinidae) belonging to the two genera Metacrinus and Saracrinus. Four species are described here, M. musorstomae is a new one. The validity of the genus Saracrinus is confirmed. The organization of the skeleton is analysed. It shows some aspects of the evolution of the Isocrinidae. Metacrinus and Saracrinus present several primitive characteristics. The study of the MUSORSTOM specimens permits a review of our knowledge about recent and fossil Isocrinidae. The recent representatives of this family are more hightly diversified than the fossil one. It becomes apparent that Metacrinus and Saracrinus are two young taxa at the outset of their adaptative radiation.
