Popis: New collections and revision of previously collected Moscovian crinoids from the Qijiagou Formation of the Taoshigo Valley near Turpan, Xinjiang Uyghur Autonomous Region, Western China, add to the generic diversity of the fauna. This camerate-rich echinoderm fauna is now recognized as containing at least one blastoid, five camerate, and ten cladid crinoid genera. The fauna shows greatest affinity at the family level with Moscovian crinoid faunas of Japan and North America. New taxa proposed are: Rhepocatillocrinus tianshanensis n. gen. n. sp.; Binariacrinus alveus n. gen. n. sp.; Bassocrinus abyssus n. gen. n. sp.; and Brabeocrinus asiaensis n. sp.
