Received on July 27, 1988; accepted on March 29, 1989 The occurrence of four species of the genus Gnathophausia taken in several series of vertically discrete hauls in the eastern North Atlantic is discussed. The five sets of samples described here were taken at the following positions: (i) six stations between 11 and 60°N, close to the 20°W meridian; (ii) three other stations between 42 and 55°N; (iii) stations in the North West African upwelling area; (iv) five stations across the Azores Front at 3035 3034°W; (v) three stations close to an area of weak hydrographic fronts between 3940°N 15°W and 4546 14°W. Distribution of species above 15002000 m are described and, where possible, correlated with the hydrographic regime.
