Most of the species mentioned in this work were already known from African coasts. Ancistroteuthis lichtensteini, mentioned by G.L. Voss (1956) for the first time outside the Mediterranean, but with doubtful identification, has never before been found on West African coasts. Moroteuthis robsoni sp. nov., has been recorded from Cape Town (South Africa) by G.C. Robson (1924) as Moroteuthis sp. Todarodes sagittatus angolensis subsp. nov. represents the species in the south Atlantic. Until recently it has never been recorded with certitude. Ornithoteuthis ? antillarum has been collected for the first time on the African coast; the genus was only known before from Japan and the Antilles. It seems premature to synonymise the genera and species of the Cranchiidae, as long as the adults and different larval stages are not better known, especially their anatomy. If L. Joubin (1933) has correctly identified his material as Teuthowenia megalops, this last species cannot be identical to Verrilliteuthis hyperborea. Opisthoteuthis agassizii has been collected for the first time on the African west coast. Octopus burryi , already known from the Cape Verde Islands, Senegal and French Guinea, has been found now in the south Atlantic, on the coast of Angola.
