Sphaerococcus intricatus C. Agardh 1822a: 333 (syntype localities: Mauritius; Hawaiian Island; 'Ravak' (Lawak); Waigeo Island; Moluccas; Indonesia). (Fig. 192) Thallus gregarious, up to 40 mm high and 150-350 ym in diameter; dark-reddish in colour with entangled, setaceous lower branches; upper parts dichotomously branched, flattened at dichotomies, with no distinct apical cell. Thallus cross-section composed of a medulla of small cells 7-10 pm in diameter, surrounded by a layer of elongated cortical cells 2-5 km in diameter; loosely packed and ovoid in surface view. Sporangia borne terminally from branchlets, up to 970 pm high and 530-660 km broad, spatulate and containing cruciate tetraspores 23-24 pm in diameter. Distribution Fiji, Micronesia, Tahiti, New Caledonia, Hawaii, Nauru, Pitcairn Island, Solomon Islands, northern Australia, Papua New Guinea, Indonesia, Philippines, Maldives, China, Tanzania. Fijian Records Kasahara 1985: 60, pl. 9, fig. 4; South and Kasahara 1992: 61. Rotuman Distribution Fapufa (F7/ USP 561); Jijlmea (J2/ USP 564, "571 USP S7: 16); Losa (LS1/ USP 562). Habitat and Remarks Forming clumps in tide pools and beneath rocky ledges. Norris (1987) transfered the genus Gelidiopsis to Ceratodictyon Schmitz (1889: 443) based on culture results, but the separate status of these entities is maintained by Price and Kraft (1991), who emphasise distinct differences in reproductive anatomy and habit between the two genera. Coelarthrum Bergesen 19 10 Coelarthrum boergesenii Weber-van Bosse 1928: 473, figs 207, 208 (syntype localities: Borneo; Saleyer Island; Paternoster Island, Indian Ocean); Bargesen 1944: 18, fig. 12; Tsuda and Wray 1977: 105; Cribb 1983: 68, pl. 20, figs 1-4; Lewis 1984: 37; Abbott 1989: 229; Tsuda 199 1 : 50. Coelarthrum coactum Okamura and Segawa in Segawa 1936. (Fig. 138a, b) Plants deep red, erect, up to 35 mm high, composed of hollow, globular dichotomous vesicles 2-5 mm high, narrow at the base and rounded at the top. Lateral ramifications and anastomosing of the vesicles common. Wall of vesicles Zlayered, the outer layer continuous and composed of obovoid cells 3-4 pm in diameter; the inner layer of much larger, closely- spaced ovoidal cells 28-42 ym wide. Cystocarps spread over vesicle surface. Gland cells not seen. Distribution Fiji, southern Marshall Islands, northern Australia, Hawaii, Ryukyu Islands, Indian Ocean. Fijian Record New record for Fiji.
Benthic Marine Algae of Rotuma Island Rotuman Distribution Ropure (Hapmak) (Rll USP 441). Habitat and Remarks Found under overhanging coral at depths of 1-2 m towards the passage on the outer reef, associated with Hypnea nidulans and Dictyopteris repens. A number of small red algae (Grzrithsia subcylindrica, Herposiphonia sp.) were epiphytic. The Rotuma specimens were more than 15 mm high and hence larger than the f. minima described by Weber-van Bosse (1928: 474) and reported in the Pacific region (Dawson 1956: 51, fig. 47; Womersley and Bailey 1970: 320). Coelothrix Bgrgesen 1920: 389 Coelothrix irregularis (Harvey) Borgesen 1920: 389; Dawson 1957: 115, fig. 23b; Taylor 1960: 488, pl. 45, fig. 3; pl. 46, fig. 4; Chapman 1963: 117, fig. 121; Trono 1969: 66, pl. 6, fig. 6; pl. 7, fig. 5; Jaasund 1976: 101, fig. 208; Tsuda and Wray 1977: 105; Magruder and Hunt 1979: 63; Cribb 1983: 68; Lewis 1984: 37; Payri and Meinesz 1985a: 511; Silva et al. 1987: 52; Littler et al. 1989: 170; Tsuda 1991: 50; Price and Scott 1992: 60, fig. 17A-D; Millar and Kraft 1993: 3 1. Cordylecladia? irregularis Harvey 1853: 156 (type locality: Key West, Florida, USA). (Fig. 195a-b) Thallus up to 4 cm long and 600 p,m in diameter, firm and pliable; axes arcuate and creeping, bearing erect, terete branches 250450 p,m in diameter. Branch apices obtuse. Thallus multiaxial, hollow, with slender central cavity up to 200 ym in diameter surrounded by a compact layer of tissue 5-6 cells thick. Cortical cells cylindrical, 40-60 ym in diameter and up to 80 ym long; innermost cells slender, consisting of longitudinal axial filaments up to 35 km in diameter, often bearing subspherical gland cells 45-60 ym in diameter. Surface cells of 2 distinct types, some longitudinally elongate, elliptical, 40-100 ym long and up to 30 p,m wide others isodiameteric, up to 25 km in diameter. Plants sterile. Distribution Fiji, Micronesia, Tahiti, Hawaii, Australia, Philippines, Japan, tropical Americas, Caribbean, West Indies, Tanzania. Fijian Record New record for Fiji. Roturnan Distribution Maka Bay (MAK181 USP 613). Habitat and Remarks Growing intertwined with Laurencia sp. within seagrass beds, at 0.5-1 m depths. Rhodymeniu Greville 1830: 48 Rhodymenia divaricata Dawson 1941: 141, pl. 23 fig. 31 (type locality: Guaymas Bay, Gonora, Mexico); Dawson 1963a: 460, pl. 89(13) fig. 2; Trono 1969: 65, pl. 8 fig. 6; Tsuda and Wray 1977: 11 1. (Figs 139, 161) Thallus violet-purple, 3-4 cm high, estipitate and expanding basally into an irregularly, divaricately dichotomous, complanate blade 270-280 krn thick and 3-8 mm broad, with
