Ultrasurface structure of the oromandibular area of a hillstream catfish Glyptothorax trilineatus Blyth 1860, an inhabitant of the sub‐Himalayan streams of India is described. Scanning electron microscopic ( SEM ) study of these areas revealed a series of punctuation elevation from the general surface epithelium. Two types (types I and II ) of taste buds ( TB ) could be identified where one type is with microvillar projections and others without any projection. Another type of cell, the basal cells, without any apical microvilli was also recorded. TB s were more concentrated on the ventral surface of the barbels. In most of the TB s, the pore is located at the centre of the elevation and surrounded by a circular area. Jaw sheath bears a single type of teeth, the papilliform teeth.
