Taxonomy
During the 1839-43 voyage of James Clark Ross naturalists found bones and baleen plates resembling a smaller version of the right whale. In his Zoology of the Voyage of HMS Erebus and Terror (1846), John Edward Gray described the new species, naming it Balaena marginata. In 1864 Gray established a new genus (Caperea) after receiving a skull and some bones of another specimen. Six years later, in 1870, he added the name Neobalaena. He soon realized the three species were one and the same: Caperea marginata (caperea means "wrinkle" in Latin, "referring to the wrinkled appearance of the ear bone"; while marginata translates to "enclosed with a border", which "refers to the dark border around the baleen plates of some individuals").
