Summary

The 33 tunicates described in this report are animals from only the greatest depths in the collections made by the U.S. Antarctic expeditions, mainly between 1962 and 1968. Ten species are new, and some of them represent types of organization unknown until now. They show a surprising faunal diversity. Some biological remarks are made in comparison with deep-sea tunicates in other oceans. A true abyssal fauna exists in the Antarctic, well separated from the shallow-water communities. Animal size is obviously larger in the south for comparable species. In spite of a limited number of samples, it appears that the proportions of the families are different in the deep Antarctic and other oceans. With this study we confirm that the abyssal tunicate fauna shows numerous common characteristics of structure at all latitudes.
