    • Abstract


      InBarbatia obliquata the mantle edge is divided into three folds as in most other lamellibranchs. Two types of gland cells are noticed in the mantle; epithelial and sub-epithelial. The epithelial glands include mucous glands, mucoprotein glands and lipid glands. The epithelial mucous glands secrete metachromatic, alcianophilic sulphated mucopolysaccharides. The sub-epithelial mucous glands are classified into two categories, according to their histochemical reactions. Some of them secrete non-metachromatic, alcianophilic sulphated mucopolysaccharides and the others secrete mucosubstances which are carboxylated.
