The nematodes recorded in the present paper were obtained from fishes caught on some of the deep-sea fishing grounds to the west of Ireland, namely, the Porcupine Bank and Irish Atlantic Slope, and from the Irish Sea. The writer is indebted to Mr S. J. Hughes and Mr J. Llewellyn for the collection of material from the deep-sea fishing grounds, excursions having been made for the purpose in a commercial trawler in August 1938 and July 1939. The majority of the nematodes were collected by Mr S. J. Hughes during the 1939 excursion, the first excursion being devoted mainly to the collection of trematodes and cestodes. A record of the trematode and cestode parasites obtained during both years has already been published (Rees & Llewellyn, 1941). Nematodes from fishes in the Irish Sea have been obtained at intervals from 1936 onwards.
