The olfactory epithelium of Wallago attu has been studied with conventional histological techniques. The elongated
olfactory rosette consists of 62 to 64 primary lamellae in each left and right rosette. The olfactory lamellae are arranged in
two rows on either side of the long raphe. Each olfactory lamella consists of two layers of epithelium separated by central
core. The olfactory epithelium in one side consists of mixed sensory and non-sensory epithelium while the other side consists
of non-sensory, non-ciliated flattened epithelial cells. The sensory epithelium in this fish contains receptor cells, ciliated
supporting cells, basal cells, mast cells and labyrinth cells. The non-sensory epithelium is composed of ciliated supporting
cells, labyrinth cells and mucous cells. Different cells of the olfactory epithelium have been correlated with the functional
significance of the region concerned in the fish studied.
