, if present, are hypodermal pentactins and/or diactins. Dermalia are stauractins and/or pentactins in various combinations. Atrialia are mainly hexactins. Microscleres are discohexasters and oxyhexasters often with hemioxyhexasters and oxyhexactins; with two or three types of discohexasters, none as calycocomes. Among the larger is a spherical form with a restricted number of secondary rays (emended from
