| Summary: | Pyura discoveryi (Herdman, 1910) (Figures 29, 30) Halocynthia discoveryi, Herdman, 1910:9. Pyura discovery Herdman 1912: 19. Primo & Vazquez 2007: 1804 and synonymy. Stations (events when several trawling operations per station): 3-6(99)-6(103)- 8-10-11 (424)-11(429)-16A-26A- 27(33)-27(45)27(46)-30(66)-31-34-35-36(68)-41-42-45-47-49A-57-62-71-79-86E.

The basal part is often prolongated by threadlike extensions on fragmented substrate. The body wall is thin with regularly distributed muscles (Fig. 29 B). A velum is present inside both siphons. The oral tentacles are poorly ramified in 3 orders of size. The dorsal tubercle is complex located inside a wide V of the peritubercular area. The dorsal lamina is made of long languets. The most ventral of the 7 branchial folds is lower on the left side (Fig. 30 B).
