Loc. 1, 4, 8, 10, 28 Known distribution. Europe ( Luther 1960 ), Brazil ( Marcus 1945b ). FIGURE 5. Live specimens of Catenulida : A–B: Stenostomum arevaloi (A: anterior end, B: tail); C-D: Stenostomum bryophilum (C: one zooid, D: two zooids); E: Stenostomum grabbskogense ; F-G: Stenostomum leucops (F: whole animal, G: anterior end); H, L: Catenula turgida (H: whole individual, L: mouth region); I: Stenostomum sphagnetorum ; J: Catenula macrura ; K: Catenula lemnae ; M: Rhynchoscolex simplex . Material. Several individuals studied alive. Description and remarks. This taxon is very characteristic with its special habitus, in comparison with other catenulids, and is therefore easily recognised. The general appearance and anatomy of our specimens is identical to that of Suomina turgida (see Luther 1960 ). Recently S. turgida was transferred to Catenula (Larsson et al . 2008.).
