The skin of Mystus gulio (Ham.) is typical of siluroids in not having any scales. Large number of mucous cells and sacciform granular cells, interspersed with taste buds, were found in the epidermis. Histochemical tests showed the presence of weakly sulphated mucopolysaccharides in the mucous cells, while the sacciform granular club cells were found to be proteinaceous, with a small amount of lipids and phospholipids. The dermis is composed of a stratum laxum and a stratum compactum. The subcutis was found to consist of loosely arranged collagen fibres and fat cells.
