Twenty-five of these are described as new. A key is included to the 98 species known at the time of writing. INTRODUCTION THIS paper deals with the genus Campylaspis (family Nannastacidae) from a number of collections made in the deep water of the Atlantic Ocean. Almost all the stations sampled were in depths exceeding 200 m and the great majority of samples were obtained by epibenthic sled dredges (Sanders & Hessler, 1969). Altogether 39 species of Campylaspis were collected, of which 25 are described here as new. A preliminary account of the distribution of the Cumacea from several of these collections has been published (Jones & Sanders, 1972) and also descriptions of a number of new genera and species (Jones, 1973 ; Reyss, 1974). Reyss (1973) has also discussed the distribution of Cumacea in the deep waters of the Mediterranean. The material studied was obtained during the following cruises : Gay Head -Bermuda transect (Woods Hole Oceanographic Institution ships), 1960-69. 'Chain' cruise (WHOI) off Brazil, April 1973. Dakar-Recife transect ('Atlantis II', WHOI), February 1967. 'Sarsia' cruise (Marine Biological Association) in Bay of Biscay, July 1967. 'Discovery' cruise (National Institute of Oceanography) near the Canary Islands, March 1968. 'Atlantis II' cruise (WHOI) Walvis Bay -Luanda, May 1968. 'Jean Charcot' cruise (Centre Oceanologique de Bretagne) in North Atlantic, August -October 1969. THE GENUS CAMPYLASPIS Including those described in this paper there are now 98 species in the genus Campylaspis known to the author. In spite of this rather unwieldy number there
