ABSTRACT: Three crinoid species of the family Bathycrinidae have been found in the Eastern Pacific; depths from 4130 to 6240 m. The species Bathycrinus complanathus was known previously only from northwestern Pacific. A new genus and two new species, Discolocrinus thieli gen. et sp.n. and Bathycrinus mendeleevi sp.n., are described. Six types of pinnule structure are distinguished within the living ten-armed crinoids of the order Bourgueticrinida. One of these types is represented in the Discolocrinus only.
