Material examined. Brazil: off São Mateus, 19 º 42 ’ S, 039º 26 ’ W, 239m, REVIZEE Bahia­ 2 Sta. #E0533 ( MNRJ 4618: 2 colonies).

Diagnosis. Colony sparsely branched up to the 5 th order, branches lateral, in angles of 45 ° – 90 ° with the lower order branches ( Fig. 6 View FIGURE 6 a); axis and branches with 4–6 longitudinal rows of primary pinnules (depending on occurrence of second anterior), arranged biserially in alternate groups along the axis. Maximum length of primary anterior pinnules 14–24 mm (average 19.30 ± 3.56 mm), maximum length of posterior primary pinnules 19– 30 mm (average 23.10 ± 3.28 mm). Secondary pinnules up to 20 mm long (average maximum length 13.00 ± 3.91 mm), in a single series on the proximal half of the primaries’ abpolypar side, up to four secondaries per primary ( Fig. 6 View FIGURE 6 c). One to three tertiary pinnules, only on the abpolypar side of the proximal secondaries ( Fig. 6 View FIGURE 6 c). Quaternary pinnules rarely present. Spines smooth or with small ornamentations (both conditions found in the same specimen), conical, acute ( Fig. 6 View FIGURE 6 d–e); inclined and usually curved towards the distal end of the pinnules; 6–10 longitudinal rows around the axis ( Fig. 6 View FIGURE 6 f–h); polypar spines 0.07–0.18 mm tall ( Fig. 6 View FIGURE 6 d), abpolypar, 0.03–0.11 mm ( Fig. 6 View FIGURE 6 e); Polyps 0.7–0.8 mm in transverse diameter, in a single series along the pinnules; 10–12 per centimeter; tentacles 0.2 mm long; oral cone elevated 0.2 mm; mouth usually sagittally elongated (emended from Opresko, 1972).

Remarks. The Brazilian colonies of Tanacetipathes hirta ( Gray, 1857)   are similar to the specimens described by Opresko (1972) and Warner (1981). The only difference is that Opresko’s material has posterior primary pinnules 2 to 6 times longer than the anterior ones. Our material has anterior primaries with a length (5.0–24.0 mm, average 11.2 mm) closer to the length of the posterior (12.0–26.0 mm, average 18.5 mm) than in Opresko’s and Warner’s specimens. However, the branching pattern, the arrangement of the pinnules and subpinnules, and the characteristics of the spines indicate that these specimens belong to the same species. The diagnosis given by Opresko (1972) was herein emended to include variations observed in Brazilian colonies, especially the relative length of anterior and posterior primary pinnules. This represents the first record of T. hirta   from the South Atlantic.

Distribution. Atlantic: Florida and Venezuela ( Opresko, 1972); Caribbean ( Brook, 1889; Opresko, 1972); Boca de Navios, NW Trinidad ( Warner, 1981); Brazil: oceanic seamount off eastern Brazil (about 19 ° S—Fig. 1).
