| Summary: | Genus Bathycrinus Thomson, 1872 Type species of the genus: Bathycrinus gracilis Thomson, 1872. Synonymy: Bathycrinus Thomson, 1872: 772; Ilycrinus Danielssen & Koren, 1877: 45; A.H. Clark, 1908a: 236; 1915: 153–154; 1917: 389–390; Bathycrinus Gislén, 1938: 14 –15; Roux, 1977: 27–28; Rasmussen, 1978: T844; Roux et al., 2002: 815, 818, 822; Mironov, 2008: 135–136; Hess, 2011a: T153. Remarks. It is difficult to distinguish Atlantic species using only external morphological characters as proposed by A.H. Clark (1908a) in his key to species in the genus Bathycrinus. B. aldrichianus Thomson, 1876 and B. gracilis Thomson, 1872 have similarly very serrated crowns profiles, and B. gracilis displays sharper median crests on the division series. However, A.M. Clark (1977: 160) suggested that “possibly further material may indicate that only one species can be recognized”. Both B. carpenteri Danielssen & Koren, 1877 from the Norwegian Sea and the Arctic Ocean and B. australis A.H. Clark, 1907b from the South ... : Published as part of Eléaume, Marc, Bohn, Jens-Michael, Roux, Michel & Améziane, Nadia, 2012, Stalked crinoids (Echinodermata) collected by the R / V Polarstern and Meteor in the south Atlantic and in Antarctica, pp. 1-22 in Zootaxa 3425 on pages 2-3, DOI: 10.5281/zenodo.209419 ... |
