Collected by Curtis Dinn by ROV hydraulic manipulator July 25, 2016, depth 876 m (67° 58.0424’ N, 59° 29.0396’ W). CMNI 2018-0196, specimen in 95% ethanol. Collected by Agassiz trawl July 25, 2017, 333 m depth (76° 19.020’ N, 75° 46.225’ W). All operations performed from the CCGS Amundsen in Frobisher Bay and Davis Strait, Canada. Description. Specimens are bright yellow with a characteristic fibrous root and soft, furrowed distal portion (Fig. 5 A–B). Spicules (Fig. 5 C–L) consist of styles/mycalostyles 514 (400–590) x 16 (12–20) µm; sigmas 20 (14.5–26) µm, anisochelae I 73 (52–88) µm; anisochelae II 37.5 (28.5–50) µm; and raphides which were rare and did not form conspicuous trichodragmas in the Frobisher Bay specimens 43 (30–53) µm n=16. Interestingly, some modified anisochelae were present where the alae were not fully developed (Fig. 5G, H). These spicules occurred in both size categories, but only in the Frobisher Bay specimens. Taxonomic Remarks . The spicule sizes of this specimen correspond to descriptions of M. ...
