A redescription of Graneledone verrucosa (Verrill, 1881) (Octopoda: Octopodidae)

Graneledone verrucosa (Verrill 1881), the type species of the genus Graneledone, is redescribed based on historical material and previously unreported specimens that have resulted from an increase in deep-sea fishing in the North East Atlantic. Graneledone verrucosa var. media (Joubin 1918) was found to be invalid and is herein synonymized with G. verrucosa. Graneledone verrucosa is shown to inhabit deep water throughout the North Atlantic; its distribution extends from 20° to 65° N and from 9° to 75° W. A revised diagnosis is given for the genus Graneledone Joubin, 1918.
