The histochemistry of the body wall and musculature of the marine triclad Palombiella stephensoni (Palombi, 1938) is investigated. The secretions of the subepidermal basiphil glands contain neutral mucopolysaccharide, and in addition the intraepidermal portion of these glands contains protein. It is suggested that this protein is a product of the epidermal cells. The subepidermal eosinophil glands contain protein. There are two types present; one is associated with the reproductive apertures, and the other is the adhesive type which assists in adhering the animal to the substrate and has been previously described. The subepidermal pigment may be a melanin.
