Resumo: | The teuthological fauna of the Gulf of Gascony is still very imperfectly understood, especially in the pelagic area. The major expeditions have rarely worked east of the line that links the Grand Sole to the reefs of Cape Finisterre. The data that we have available for the region come from independent observations by H. FISCHER and L. JOUBIN (1906) and by L. JOUBIN (1895, 1900, 1920 and 1924). The most important research work is thanks to J. BOUXIN and R. LEGENDRE (1936), who studied very many stomach contents of tunny.  In 1966 and 1967, the Thalassa had the opportunity to conduct 17 deep pelagic catches using an Isaacs-Kidd net, at immersions spaced out between 500 and 1,600 metres. They brought in twelve species of cephalopods: Heteroteuthis dispac (RUPPEL), 1845, Onychoteuthis banksi (LEACH), 1817, Brachioteuthis riisei (STEENSTRUP), 1882, Catliteuthis reversa VERRIL, 1880, Mastigoteuthis grimaldii (JOUBIN), 1895, Mastigoteuthis sp., Helicocranchia pfefferi MASSY, 1907, Taonius megalops (PROSCH), 1849, Taonius pavo (LESUEUR), 1821, Galiteuthis armata JOUBIN, 1898, Vampyroteuthis infernalis CHUN, 1903, Vitreledonella richardi JOUBIN, 1918.  This material, supplemented by a few pelagic cephalopods caught using a classic bottom trawl at a depth of 1,000 metres, will be studied in the scope of a study devoted to all the mesopelagic fauna harvested during these catches. However, three species merit special attention and will be the subject of this research work: Vampyroteuthis infernalis, Taonius pavo, which are new for the gulf, and Helicocranchia pfefferi, for which we will attempt to re-establish the taxonomic status cast into doubt by some authors.
