1. By means of columnar and thin-layer chromatography, the presence of carotenoids in Eudiaptomus amblyodon was studied. 2. The following carotenoids were found: (a) in eggs: β-carotene (2·73 per cent), isozeaxanthin (5·16 per cent) and astacene (20·16 per cent); (b) in pink copepoidal form: isozeaxanthin (5·04 per cent), 3,4-dihydroxy-β-carotene (1·20 per cent), 1′,2′-dihydro-1′-hydroxy 4-keto-γ-carotene (1·25 per cent) and astaxanthin (86·44 per cent); (c) in bluish copepoidal form: canthaxanthin (1·72 per cent), 4-hydroxy-4-keto-β-carotene (5·29 per cent), isozeaxanthin (8·78 per cent) and astaxanthin (77·15 per cent); (d) in the mature female: isocryptoxanthin (1·48 per cent), 4-hydroxy-4-keto-β-carotene (2·66 per cent), lutein (7·29 per cent) and astaxanthin (76·56 per cent).
