N2  - The range of presumably polyketidal constituents in comatulid crinoids has been extended by examination of Lamprometra palmata gyges Bell to include three 10,10&#8242;-bianthrones derivable from the known crinoid constituents, 1,3,8-trihydroxy-6-propyl-9,10-anthraquinone and the corresponding 6-(1&#8242;-hydroxypropyl) quinone . From other species, a 1,1&#8242;- bianthraquinone, a phenanthroperylene-7,14-quinone and probably 8- acetyl-1,2,4,5,7-pentahydroxy-9,10-anthraquinone have been identified in addition to other pigments previously known from crinoids. The polyketides present in particular comatulid crinoids may be determined by natural selection from a wide range available to crinoids generally, rather than by chemotaxonomic considerations.
