British Antarctic (“Terra Nova”) Expedition, 1910 Natural History Report


THERE are very few groups of invertebrate animals of which it can be said with any probability that nearly all the existing species have now been discovered. This claim was made some years ago by Dr. H. J. Hansen as a result of his extensive studies on the Crustacea of the order Euphausiacea. It is supported by the fact that, in the report on the very large collections of this group made by the Terra Nova expedition, Prof. Tattersall has not found it necessary to describe a single new species. He discusses the characters and synonymy of a number of the species and describes a series of the larval stages of Euphausia longirostris, which is shown to differ from some of its congeners in having a prolonged larval life and in reaching an unusually large size before assuming the adult form. A considerable part of the memoir is devoted to discussing the distribution of the species obtained in the three areas chiefly explored, the Atlantic, the New Zealand region, and the Antarctic and Subantarctic zones south of New Zealand.
