samples of the bottom deposits, and this was frequently in 
use during the cruise. A new species of Copepod, which 
was obtained in this manner from muddy sand dredged in 
Port Erin Bay at a depth of five fathoms, has been named 
Jonesiella hyene, in honour of the old gunboat. 
In the afternoon the ‘‘ Hyena’’ made two runs from 
Port Hrin southwards to the Calf, dredging homewards 
with the wind, and got two excellent hauls, which 
contained, amongst other things, the rare coral-like 
Sarcodictyon, the flat pentagonal starfish Palmipes, the 
remarkable parasitic sea-anemone Adamsia, which is 
always found in company with a particular hermit crab 
(Pagurus prideauaw), Echinocyamus pusillus, Stichaster 
roseus, Porana pulvillus, Lyonsia norvegica, Ascidia 
venosa (with Leucothoe spumcarpa in the branchial sac), a 
sponge (Hsperella florewm) new to the district, and various 
rare crustacea and mollusca. 
Evectric Light EXPERIMENTS. 
After dark, on two consecutive nights, the electric light 
was used for a couple of hours in collecting bottom and 
surface free-swimming animals around the ship, in much 
the same way as during the previous summer’s cruise. 
The first application of this important method of 
collecting appears to have been made by the United 
States Fish Commission in 1884, on board the steamer 
“Albatross.” On that occasion an arc lamp was merely 
suspended above the surface of the water, and it was 
found to attract Amphipods, Squids, and young fish to 
the surface. In the following year the same naturalists 
experimented further by lowering an Edison incandescent 
lamp into the water, with similar good results. The Fish 
Commission do not give any details in regard to the
