— The ocellar pigment of Spirocodon saltatrix extractable with phosphate buffer and acidified methanol was considered to be a substance closely related to or identical with xanthommatin, from its behaviour on paper and thin‐layer chromatography and from the position of the absorption maxima in the ultra‐violet and visible ranges of the spectrum in various solvents. The infra‐red spectrum also supported this view. The pigment extracted with cetyltrimethylammonium bromide was gel‐filtered through a column of Sephadex G 100. The pigment was eluted fairly quickly and the elution pattern was narrow, indicating that the eluted pigment is large as well as homogeneous in its molecular size. The gel‐filtered pigments from medusan ocelli and fly ommatidia underwent an almost indentical photoreduction under anaerobic conditions.
