Remarks. Reverter-Gil et al. (2011) recently redescribed type and other material of Crepis longipes  from the Iberian continental shelf. Although the authors stated that one of the Travailleur stations from which Jullien (1882) originally recorded the species was Galicia Bank, this was a mistake owing to a wrong interpretation of the geographic position. During the Travailleur campaign the longitude was referenced to the Paris meridian, which nowadays makes it necessary to correct the original reading to the Greenwich meridian ( Ryland 1969). After corrections, that station is situated on the continental slope of northern Iberia. Nevertheless, we are able to demonstrate here that C. longipes  does, indeed, occur on Galicia Bank, which marks the first record of this species off the continental shelf.

SD, standard deviation; N, number of measurements

Souto et al. (2014) described the ovicell and operculum of C. longipes  for the first time; both characters were also observed in the specimens from Galicia Bank ( Figs 18, 19, 22View FIGURES 18 – 22), and are identical with the previously recorded material. Ovicells are terminal, the ooecium being formed by a distal kenozooid that is concealed from frontal view, and which distally buds the caudal part of the next autozooid in a row.

Several specimens were found at four Galicia Bank localities ranging from 770 to 860 m depth. The colonies mainly encrust coral skeletons but also rocks, while one colony was found on a piece of slightly lithified foraminiferal sand.
