Oikopleura in the Gulf is especially noteworthy, since it has not been recorded previously on this side of the x\tlantic south of Bafiins Bay, though known in European waters as far south as the Shetland Is- lands (Lohmann, 1896, 1910). Thanks to Lohmann's excellent de- scriptions and figures (1896, p. 72, taf. 14, fig. 6, 7, 10; 1910, p. 15, fig. 16, 17) it is easily recognized, its chief difference from the closely allied 0. labradorensis being the presence of many small, dendritic,.
