Tractolira delli, a new Volutidae (Mollusca: Gastropoda: Neogastropoda) from the abyssal plains off Antarctica
A new deep-sea species of Volutidae in the genus Tractolira is named from material collected by the United States Antarctic Program in and around the Ross Sea, eastern Antarctica, and from one locality in the Subantarctic region. Tractolira delli new species is most similar to T. sparta Dall, 1896,...
