A new hydrozoan species, Sarsia marii, is described by using morphological and molecular characters. Both morphological and 16S rDNA data place the new species together with other Sarsia species near the base of a clade that developed, walking tentacles in the medusa stage. The molecular data also suggest that the family Cladonematidae (Cladonema, Eleutheria, Staurocladia) is monophyletic. The taxonomic embedding of Sarsia marii n. sp. demonstrates the usefulness of 16S rDNA sequences for reconstructing phylogenetic relationships in Hydrozoa., No disponible

The present paper addresses the question of territoriality with reference to the Swiss minority language Romansh, taking account of the contributions of jurists who were dealing with the legal situation in Switzerland and showing the importance of the principle in the common perception of the national languages of Switzerland. Furthermore, insights from a philosopher, Philippe Van Parijs, who has been contributing to a conception of hierarchy between languages, are considered. Concerning the Romansh area, the efforts that have been made to enshrine the territoriality principle in the legislation are outlined and sociolinguistic data are included in order to verify the suitability of conceptions and solutions proposed by the authors cited.
