Abstract
Several female specimens of a new Philometrid nematode were collected by the writer from under the skin of the fish Bagrus bayad (Forskal) in the head region, just lateral to the sides of the mouth opening. The worms could be seen with some difficulty under the skin, and each fish harboured 2–4 worms. About thirty per cent of the fishes examined were infected and the parasite was prevalent from the month of December to the end of February or early March only.
