摘要：

Rouxicrinus vestitus new genus, new species, collected during submersible dives at depths of 421-887 m near Barbados, Colombia and the Bahamas is described, and notes on ecology are included. It is referred to the family Septocrinidae Mironov, 2000, which now comprises three genera, Zeuctocrinus A. M. Clark, 1973, Septocrinus Mironov, 2000, and Rouxicrinus new genus. This new genus differs significantly from both Septocrinus and Zeuctocrinus in having numerous low columnals in the proxistele, which tapers toward the crown, first pinnule arising more proximally, thorns on brachials and pinnulars, and a thick covering of soft tissue on arms and pinnules.
