V. Preliminary report to Professor Wyville Thomson, F. R. S., Director of the Civilian Scientific Staff, on crustacea observed during the cruise of H. M. S. 'Challenger' in the Southern Sea
In the following paper it is intended to give a short account of the Crustacea found at the bottom as well as on the surface of the sea during the antarctic cruise of H. M. S. ‘Challenger.’ Our expedition, as is probably well-known to most readers, left the Cape on December 17, proceeded towards the Prince-Edward Islands, and landed on one of them. Between these islands and the Crozets, on which landing was impossible, we had several successful deep-sea dredgings. From the Crozets we sailed to Kerguelen, where we stayed nearly a month, and where a great deal of shallow-water dredging was done. Proceeding from this large island to the south, we penetrated beyond the antarctic circle, and had four successful deep-sea dredgings near the ice-barrier. On our way to Australia we were able to trawl five times. The surface animals were generally collected by the towing-net at every station by lowering the net to a depth of 50-100 fathoms, where, as experience has shown us, nearly the same quantity of animals are found during the day which at night are to be got from the very surface. In fine nights, when the ship»was gliding very slowly through the water, the net was of course always put out, and its contents were carefully preserved; but during our antarctic cruise such nights were rare, so that in most cases we had to lower the net in the daytime, during the manipulations of dredging and sounding.
