Henricia cylindrella ? (Sladen, 1883) Reports for the Azores: Cribrella abyssalis Perrier, 1894 —? $ Koehler 1909: 102; Henricia abyssalis (Perrier, 1894) — Farran 1913: 26; Mortensen 1927a: 118; Henricia cylindrella (Sladen, 1883) —? $ Madsen 1987: 231–235, figs. 2g, 21–23;? $ A.M. Clark & Downey 1992: 390–391, figs. 60a(?), f–g, pl. 93, fig, B, pl. 94, fig. G; García-Diez et al . 2005: 47. Type locality: NW Scotland (59°29’N, 07°13’W) (lectotype). See: Grieg (1932: 30, as Cribrella abyssalis ); Madsen (1987); A.M. Clark & Downey (1992). Occurrence: Northeast Atlantic, from the northern Rockall Trough south to the Porcupine Seabight, SW Ireland (A.M. Clark & Downey 1992) and the Charlie-Gibbs Fracture Zone (Dilman 2013); probably also extending to the Azores and to waters between Canaries and Morocco (Perrier 1894, Koehler 1909). Depth: 1,015–2,620 m (Dilman 2013);? AZO: 1,482–1,805 m (Koehler 1909). Habitat: soft substrates (? AZO: Globigerina ooze; Koehler 1909). Remarks: in a preliminary report, Perrier (1885c) described a new species Cribrella abyssicola , which in his 1894 report was renamed Cribrella abyssalis based on material collected by Talisman from Morocco. Following the previous author, Koehler (1909) reported the same species from Princesse Alice material collected in the Azores, Portugal and NW Africa. In a review of the genus Henricia in the NE Atlantic, Madsen (1987) examined a single specimen (R = 43 mm, r = 6 mm) identified as Cribrella abyssalis , collected by Talisman in the Azores at a depth 1,257 m. Though Perrier (1885c, 1894) did not list any material from the Azores under his newly described species, the material examined by Madsen could represent an unreported specimen ( Talisman , sta 127: 38°38'00"N, 28°20'46"W, 1,257 m). Madsen proposed that Perrier’s species should be synonymized with Sladen’s Henricia cylindrella . Nevertheless, this author noted that the specimen from the Azores presented slight differences ( i . e . shorter arms) than the typical H . cylindrella . ...
