| Abstract: | The colouration of living specimens of Lineus atrocaeruleus (Lineidae, Nemertea) is bluish or brownish black with many transverse yellow rings. The pigments responsible for the colouration are granular and are elaborated by epidermal and dermal pigment cells, both of which contain uroporphyrins. Granules of melanic nature occur in the dermal pigment cells. The significance of the epidermal pigment cells is discussed. |
