All these fishes, if we except, perhaps, Bathymicrops regis, were prob- ably captured while the trawl was being hauled in. There were thus no undoubted bottom-fish in this long haul with our large appliance, and taking everything into consideration, we had caught extremely little. Chapter VII. deals more fully with the signific- ance of this result. We were interested to find a fragment of a sea-pen (C/m- bellula giintkeri, Fig. 70) which con- tinued shining brightly on the deck, thus furnish- ing fresh proof of the well-known fact that some of the lower animals from the profound- est depths emit light. While towing the trawl we made some interesting observations on the pelagic animal life, as we put two tow- nets on the trawl wire, the one being- towed at about 40 metres, and the other at about 2000 metres, and during the whole of the day we took samples from the surface. The tow-net at 40 metres contained a mass of red copepods, which were not observed at the surface during the daytime, but suddenly appeared as soon as it grew dark, soon after 6 The surface plankton comprised PJiysalia, a great many molluscs, such as Ianthina and Pterotrachea, one of the remarkable little. sj FlG. 70.
