Two species of algae were living symbiotically with a hard brain coral, Fa@ia, harvested in the environs of the Flinders Island Group on the Great Barrier Reef in Australia. One of the algae has the microscopic appearance and pigment corn position of dinoflagellates (Halldal, 1968, Jeffrey and Haxo, 1968) and it contrib utes the dark brown color to the coral tissues which form a surface layer over the colony. This alga resembles Symbiodiniuni microadriaticum Freudenthal. Green algae lived inside the spherical coral forming another colored layer (Jeffrey, 1968) , and there was an intermediate pale green (nearly white) layer between these brown and green layers. The green algae seemed to be of mixed genera and species, most of them probably belonging to Ostreobiuni Reineckei Bornet within the order Siphonales. The present paper describes the in vivo absorption spectra of these algal layers as well as the spectral distribution. EXPERIMENTAL METHODS The samples of Favia pallida DaIla were harvested in the environs of the Flinders Island Group, and were kept in running sea-water aquaria on the open deck of the research vessel. The spectral data presented in this paper were observed for the sample which was 12 cm in diameter and 8.5 cm in thickness
