In the Magellan region, Ascidiacea appear to be a dominant invertebrate group at depths from 5 - 20 m. Most of the present collection, made by scuba divers in the Strait of Magellan, have a geographic range limited to Patagonia, the Falkland Islands, South Georgia, the South Shetland Islands and north of the Antarctic Peninsula. The exceptions are two circumpolar species: Distaplia cylindrica (Lesson, 1830) and Didemnum studeri Hartmeyer, 1911. One new species is described.

Part of the echinoderm material (Echinoidea and Asteroidea) sampled by 59 Agassiz trawls during the 'Victor Hensen' Campaign 1994 is summarized in a preliminary species list. In total, 7 echinoids and 21 asteroids have been determined to species from the area between Paso Ancho and Cape Horn. All of them were known from the area before.
