'''CHESSBOARD PATTERN''' - a [[chamberlet arrangement]] in superposed chamberlet layers in alternating positions resembling those of a chessboard: in one layer, the position of the chamberlets corresponds to the black fields, in the following layer to the white fields, as in ''Sphaerogypsina''. The outline of the chamberlets may be quadratic, polygonal or somewhat irregular. This three-dimensional array corresponds to the annular chamberlet arrangement, that is alternating radial positions in the second dimension.
