    • Abstract

       

      In the crabMenippe rumphii, embedded in the connective tissue of the oesophagus there are salivary or oesophageal glands. Each gland is made up of four to eight conical cells with a central cavity. Histochemical observations on the gland cells have shown the presence of some neutral and weakly acidic sulfated mucopolysaccharides. The glands are positive to toluidine blue showing gamma metachromasia. Similar type of glands are also observed in the walls of the hindgut. The cytochemical details of the gland cells have been discussed in detail.
