it abounds. 
We dredged many Holothuriz; notably everywhere 
below 209 or 390 fathoms the delicate little Hehino- 
cucumis typica, M. Sars; and Psolus squamatus, 
KOREN, which does not seem however to be common, 
though we dredged it in great profusion on one occa- 
sion in the ‘ Lightning,’ its white scaly disks showing 
out against the smooth black pebbles of Fieroe basalt 
to which they were attached. Holothuria ecalcarea, 
SARS, was met with occasionally, and formed another

interesting addition to the British fauna. It always 
had a peculiar effect coming up among a number of 
much smaller and more delicate things, like a massive 
German sausage twenty or thirty centimetres long. 
In the characteristic hauls in the cold area we met 
with some very interesting crustaceans, one or two of 
which I figure as they are highly suggestive of the 
source of the cold water. They are some of the 
gigantic forms of amphipoda and isopoda of the 
Arctic sea.
