Amigdoscalpellum tenue (Hoek, 1883) Fig. 10 Scalpellum tenue Hoek, 1883: 119, pl. IV, figs 20–21, pl. X, fig. 6; Gruvel, 1912: 345; Nilsson-Cantell, 1938: 8. not? Scalpellum tenue Annandale, 1906a: 142. Amigdoscalpellum tenue : Zevina, 1981a: 292–293, fig. 220 (2). Material examined. Holotype NHM UK 2013.1080, Stn 146: Indian Ocean, Antarctic and Southern (North East of Prince Edward Island); 2515 m. Diagnosis. The diagnosis was given by Hoek (1883), but the appendages have not yet been described. Distribution. Indian Ocean, Antarctic and Southern. Known depth 2516 m. Remarks. This species is known only from Hoek’s original description of the holotype. Newman & Ross (1971: 67–68) noted a close resemblance between this species and Teloscalpellum latuscutum (Newman & Ross, 1971) from the southwestern edge of Southeast Pacific (4758–4804 m) and Amigdoscalpellum semisculptum (Pilsbry, 1907a) from the Gulf of Mexico (512 m). The major feature uniting these three species is the very narrow inframedian latus, which is triangular and close to linear in A. semisculptum and A. tenue , but rectangular in A. latuscutum , nearly reaching the upper latus. In the “Challenger” specimen we also found that the carina has low but strong bordering ribs, as in A. semisculptum and P. latuscutum .
