ABSTRACT
The biological contribution of the Challenger Expedition is most tangibly commemorated by the vast collections of material brought home (see Chapter 1) , now mainly in the Natural History Museum in London, and the fifty volumes of the official scientific reports. More than 18,000 of the 30,000 or so pages in these reports are devoted to the marine biological collections and contain an enormous amount of systematics, which have formed the basis of the subsequent taxonomic study of most deep-sea and many shallow-water marine groups.
