Depth, 775 and 420 fathoms; deposit. Green Mud, containing only a trace of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chalk Exp.). 
At 2 A.M. observed Omae Saki lighthouse on port bow, and at 6 a.m. observed land 
about Iro-o-Saki. At 1 P.M. stopped and sounded in 775 fathoms. At 2 p.m. put over 
trawl, veering 1000 fathoms. Obtained serial temperatures. Found on sounding at 
3.15 P.M. that the ship had drifted into 420 fathoms. At 3.45 p.m. commenced heaving 
in tniwl, which was hauled up very slowly and with great strain. At 4.45 p.m. trawl 
came up, considerably damaged, the net being torn in several places. The bag contained 
a quantity of stones and gravel, along with several specimens. At 5 p.m. proceeded 
towards Yokoliama, anchoring there at 8.40 p.m. 
The following species are recorded in the Zoological Reports from the trawl at this 
place : —
