BIOICE sample 2065 (one specimen in one SEM stub IMNH 24933; 66 º 41 ' 88 ''N; 20 º02' 98 ''W, 148 m). BIOICE sample 2152 (six specimens in three SEM stubs IMNH 24934 to IMNH 24936; 66 º08' 91 ''N; 17 º 35 ' 85 ''W, 198 m). Additional material examined. Naturhistorisk Museum, Universitetet i Oslo, C- 1528. Bundefjord (Kr.ania), 45–50 fr., 15.09. 1908 (Wollebaeck det.). Two vials with 68 and 38 specimens respectively; one vial revised by A. Wollebaek in 1908 and one by T. Holthe in 1975. Occurrence. Present in a wide range of depths and temperatures, both in cold northern and warm southern waters. Depth range: 173−1951 m; temperature range: -0.8ºC to 7.2ºC. Distribution. Since Williams (1984), the cosmopolitan status of T. stroemii has been questioned, and its distribution is now thought to be limited to Boreo-Arctic waters of the Atlantic Ocean (Hutchings & Peart 2000). This species was previously reported in Icelandic waters by Wesenberg-Lund (1951). Remarks. The characteristics of the Icelandic specimens correspond fairly well with the expanded redescription of specimens of T. stroemii from Norway provided by Hutchings and Peart (2000). Lateral lappets are present on segments 3–7 declining in size posteriorly and forming dorsal rounded projections on the same segments (Fig. 11 a–c). However, their development varies among the specimens, being usually larger on segments 4–6 (chaetigers 2–4) and particularly on the fifth (Fig. 11 c). These differences may be due to age or sexual maturity so ...
