The shape of retracted mouth and mantle-cavity openings may be diagnostic (Fig. 15C. Hi. The cuticle and epidermis can be either thick or thin relative to the si/e of the species. A thick cuticle can occur with a thin epidermis, or a thin cuticle with a thick epider- mis, or they may he the same thickness. Gland cells of the epidermis, termed papilhic. may ha\e long stalks or he unstalked (Fig. IB, FP); their (unction lias not been deter- mined. The epidermal spicules can be (I) skeletal (=tangen-.
