Abstract
The scythe fish (Pseudogobio esocinus T. et S.) is a bottom-feeding fish and has very broad queer lips. The present report deals with the histological study of them. On the lips are found many granular processes in which numerous taste-buds can be observed. Although they are numerous in number, they are distributed mainly about the apex of each process and comparatively few in other places, becoming less and less until they are none at the bottom. Their shape and structure are nearly similar to that of barbels of the mud leach which have been reported to have a flask-like shape and slender sensory cells comparatively closely set by MIYADI (1929) and SATO (1936, 37), and also similar to that of the skin of Rita rita H. by AHSAN-UL-ISLAM (1951).
It may be inferred from above mentioned facts that the granular processes on the scythe fish lips play an important role when finding food.
