Abstract

An incomplete skull of unknown sex of a sub-adult spectacled porpoise (Phocoena dioptrica Lahille, 1912) was collected at Macquarie Island (54°30’S, 159°00’E) in July 1957. Cranial measurements are given, and the specimen is compared with other phocoenids. This is the second specimen of P. dioptrica reported from the subantarctic southwest Pacific, and this record adds support to the suggestion that the species may have a circumpolar distribution in subantarctic latitudes.
