Gellius carduus var. magellanica Ridley & Dendy, 1886 (Fig. 3I) Gellius carduus var. magellanica Ridley & Dendy, 1886: 333; Ridley & Dendy 1887: 40, pl. XIII fig. 6. ? Adocia carduus; Burton 1932: 274. The variety was described by Ridley & Dendy from Strait Magellan, Challenger Expd. Stat. 311, 52.7582°S 73.7667°W, depth 448 m (wet holotype specimen BMNH 1887.5.2.256). It differed from the typical variety described as Gellius carduus by Ridley & Dendy from Crozet Islands Challenger Exped. Stat. 148a, 46.8833°S 51.8667°E, depth 439–1006 m, and nearby Prince Edward Islands, syntypes BMNH 1887.5.2.254, 258 and 263) in habitus (oval massive vs leaf-shaped), oxea shape (true oxeas vs strongylote oxeas), and oxea size (490 vs. 600 µm). Burton (1932: 274), treating sponges from the Falkland Islands and Magellan region synonymized the two varieties and included Gellius laevis Ridley & Dendy, 1886 into an extended species Gellius carduus (as Adocia). For the combined species Burton cited oxea ... : Published as part of Van Soest, Rob W.
