Description
Summary:Tromikosoma uranus ? (Thomson, 1877) Reports for the Azores: Phormosoma uranus Thomson, 1877 —? $ Agassiz 1881: 103–104, pl. 18c, fig. 12; non Phormosoma uranus Thomson, 1877 — Koehler 1898: 7, 10–15, pl. 1, fig. 1, pl. 3, figs. 5–6, pl. 9, figs. 49, 50. [misidentified H. petersii]; Echinosoma uranus Thomson, 1877 —? $ H.L. Clark 1925: 57. Type locality: Gorringe Ridge, off Portugal (36°23’N, 11°18’W). See: Mortensen (1935: 168–170, pl. 6, figs. 2– 3, pl. 75, figs. 19–21). Occurrence: Northeast Atlantic, from off Portugal (Thomson 1877) to off the Western Sahara coast (Mortensen 1927b) and the?Azores (H.L. Clark 1925). Depth: 938– 2,745 m (Mortensen 1935);? AZO: 1,830 m (H.L. Clark 1925). Habitat: most probably a bottom-feeder on soft sediments. Remarks: Tromikosoma uranus was recorded from the Azores based on specimens collected by the H.M.S. Challenger (Agassiz 1881), Hirondelle and Talisman (Koehler 1898). Except for H.M.S. Challenger material, all other were re-examined and re-assigned to H. petersii (Mortensen 1903; Koehler 1909; Mortensen 1935). The specimen from H.M.S. Challenger was a young specimen (7 mm) in a poor state of preservation, which rendered the identification impossible (see Mortensen 1903). The occurrence of this species in the area should be considered with caution, until new material is retrieved from the Azores (see remarks under T. koehleri).
