    • Abstract


      The prismatic and nacreous layers in the shells ofBarbatia obliquata, Modiolus metcalfei, Pinna vexillum andMytilopsis sallei vary in thickness, though they show similar affinity for both basic and acidic dyes. Histochemical evidence revealed that these layers contain proteins as well as acid mucopolysaccharides. Quinone-tanning is observed in the nacreous layer.
