Bougainvillia sp.

(fig. 2A–B)

Material examined. Stn. 3: 01.04.2008 —two 4 mm high monosiphonic, sterile stems, on concretions.

Description. Colonies small, ca. 4 mm high, with erect, monosiphonic, irregularly branched cauli. Perisarc covered with detritus, slightly corrugated at bases of branches, elsewhere smooth; pseudohydrotheca present, evenly covered with detritus. Branches short, each with a terminal hydranth; the latter with roundedconical hypostome encircled by single whorl of 11–13 filiform tentacles. Gonophores absent. Nematocysts (undischarged): microbasic euryteles (5.8–6.1) × (2.4–2.7) µm; desmonemes (3.8–4.1) × (2.4–2.7) µm.

Remarks. The present material belongs, without any doubt, to Bougainvillia Lesson, 1830 . However, the lack of gonophores makes it unidentifiable to species level. Several members of the genus have been reported from the Caribbean (see Vervoort 1968). Additionally, Calder (1988b) recorded B. muscus ( Allman, 1863) from Bermuda.
