Abstract
Four specimens of Farrea herdendorfi Duplessis & Reiswig, 2004 are described from the depth 2428–2630 m in the Charlie-Gibbs Fracture Zone area, northern Mid-Atlantic Ridge. Specimens were collected on cruises of the RRS James Cook (in 2007 and 2010) as part of the ECOMAR project. The species was originally reported from off South Carolina (USA), and subsequently from Campos Basin (SE Brazil). New specimens slightly deviate from specimens in the type series, apparently owing to complete lack of onychohexasters, which are considered here to be of minor importance.
