Francesc Pagès, Josep Maria Gili Sardà

• Nine species of siphonophores were collected during the Belgian¿Magga Da? Expedition in a transect from South Africa to Antarctic waters between December 1966 and February 1967. Two species were recorded for the first time in Antarctic waters: Bargmannia elongata and Nanomia bijuga. The bracts of Thalassophyes crystallina were found and described from material collected during this expedition. Two substantial colonies of Mica micula allowed a redescription of species and its systematic position is discussed.
