Abstract:
The Recent brachiopods described herein were collected during dredging operations of several research vessels: the United States R/V Eltanin (alias Islas Orcadas while on loan to Argentina) in Antarctica, in the subantarctic waters of the Atlantic around South Georgia and the South Sandwich Islands, and in the Scotia Sea; R/V Hero dredging in Antarctic waters; R/V Anton Bruun operating along the west coast of South America; the initial cruises of R/V Rafale and Thierry operating in the Gulf of Guinea off the coast of West Africa.
