the present morphochemical analyses indicate that ( 1 ) the mucosubstances of the epidermis are found within two well differentiated cell types , goblet and clavate cells which elaborate a neuraminic acid containing mucosaccharide with vicinal hydroxyl , sulfate and carboxyl groupings and a glycoprotein respectively and ( 2 ) the mucosubstances of the gill and intestinal epithelia are found within goblet cells which elaborate a mucosaccharide with histochemical properties comparable to those of mucosaccharide within the epidermal goblet cells .
