The radiolarian species, Protocystis thomsoni (Murray), is reported for the first time from the northeast Pacific Ocean. A detailed study indicated that this species shows considerable variation in the shape of the shell, as well as in the peristome and its teeth. Statistical treatment indicated that the shape of the shell has no taxonomic significance. The local distribution of the species and its position within the water column are discussed and compared with those of specimens from other parts of the world.
