Abstract

Species of the late Osagean and early Meramecian primitive cladid crinoid genera Atelestocrinus, Barycrinus, Cestocrinus, Costalocrinus, Cyathocrinites, Meniscocrinus n. gen., Parisocrinus, Pellecrinus, and Saccosomopsis from Illinois, Indiana, Iowa, Kentucky, Missouri, and Tennessee are reviewed, redescribed, and redefined from study of type material, museum collections, and field collections. Nomenclatural and systematic acts include the following: 1) Barycrinus spurius (Hall, 1858) is a senior synonym of Cyathocrinus tumidus Hall, 1858, C. protuberans Hall, 1858, and B. mammatus Meek and Worthen, 1873; 2) B. rhombiferus (Owen and Shumard, 1852a) is a senior synonym of C. sculptilis Hall, 1860, C. thomae Hall, 1860, C. hoveyi Hall, 1861a, C. wachsmuthi Meek and Worthen, 1861, B. herculeus Meek and Worthen, 1868, B. pentagonus Meek and Worthen, 1873, B. striatus Worthen, 1875, B. boonvillensis Miller, 1891b, B. formosus Miller and Gurley, 1894, B. washingtonensis Miller and Gurley, 1895, and B. elrodi Miller and Gurley, 1896a; 3) B. magister (Hall, 1858) is a senior synonym of C. solidus Hall, 1861a and B. magnificus Meek and Worthen, 1868; 4) B. stellatus (Hall, 1858) is a senior synonym of C. bullatus Hall, 1858, C. angulatus Meek and Worthen, 1860, C. quinquelobus Meek and Worthen, 1865, and B. astericus Van Sant, 1964; 5) B. crassibrachiatus (Hall, 1860) is a senior synonym of B. princeps Miller and Gurley, 1890a; 6) B. geometricus Meek and Worthen, 1873, is considered a nomen dubium; 7) B. benedicti (Miller, 1891a) is considered a nomen dubium; 8) Cyathocrinus signatus Miller and Gurley, 1894, is assigned to Cestocrinus and is a senior synonym of Cestocrinus striatus Kirk, 1940; 9) Cyathocrinites iowensis (Owen and Shumard, 1850) is a senior synonym of C. malvaceus Hall, 1858, C. divaricatus Hall, 1858, C. rotundatus Hall, 1858, C. viminalis Hall, 1861a, C. parvibrachiatus Hall, 1861a, C. hamiltonensis Worthen, 1882, C. nodosus Wachsmuth and Springer, 1890, C. brevisacculus Wachsmuth and Springer, 1890, C. opimus Miller and Gurley, 1890a, and C. gurleyi Miller, 1891a; 10) C. kelloggi (White, 1862) is a senior synonym of C. subtumidus Meek and Worthen, 1865; 11) C. farleyi (Meek and Worthen, 1866b) is a senior synonym of C. andersoni Miller and Gurley, 1894, C. granulosus Rowley, 1902, and C. snivelyi Rowley, 1902; 12) C. harrodi (Wachsmuth and Springer, 1880) is a senior synonym of C. boonvillensis Miller, 1891b, C. gorbyi Miller, 1892b, and C. astralus Kammer, 1984; 13) Meniscocrinus n. gen. is described and M. magnitubus n. sp. is assigned to this new genus; 14) C. labyrinthicus Miller, 1891a, is assigned to Parisocrinus; 15) C. intermedius Hall, 1858, is assigned to Pellecrinus; and 16) C. insperatus Lyon, 1869, is assigned to Saccosomopsis and is a senior synonym of C.? poterium Meek and Worthen, 1870.
