Stn. 7 , 23.i.2012 , 6 m, M012 : sterile colony growing over varied debris fixed on a portion of fishing wire. Remarks . Hydrorhiza creeping, giving rise to short, smooth pedicels, each carrying a 520–730 µm long and 310–365 µm wide hydrotheca; margin slightly flaring, 360–400 µm wide at aperture. The cnidome comprises four types of capsules: 1) small, ovoid microbasic heteronemes, ca . 5.0×2.6 µm, of rare occurrence in the coenosarc; 2) fusiform microbasic mastigophores, (6.1–6.9)×2.1 µm, abundant in the tentacles and the coenosarc; 3) tubular microbasic mastigophores with a rather prominent, lateral "beak" at insertion of the shaft, ca . 6.6×2.1 µm, rarely occurring in the coenosarc; 4) large, elongate-ovoid microbasic heteronemes, (17.8–18.6)×(5.3–5.8) µm, abundant in the hydrorhiza. Geographical distribution . Only known from Martinique .
