. Lose strange organs protuded by certain caterpillars from the head, and by the beetle- 
genus Staphyluius from the tail. Fritillaria was also present to-day. This remarkable 
genus of Appendicularians was first found at Messina by Fol ; it has a very elongated 
transparent bod} 7 , in which testis and ovary are well separated from each other and from 
the digestive and branchial apparatus, so that from this genus a good view of the 
complicated anatomy of Appendicularia can be easily obtained.”

Depth, 2500 fathoms; deposit, Globigeriua Ooze, containing 71 ‘70 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chalk Exp.). 
At 8 a.m. shortened and furled sails, and got up steam to sound and trawl. At 
.• a.m. put trawl over. At 9.20 a.m. brought ship to wind, and sounded in 2500 fathoms. 
At 1 p.m. lowered cutter to ascertain surface current. At 2 p.m. obtained serial tempera- 
‘(i!*- down to 1500 fathoms. At 5.30 p.m. trawl came up with several specimens. 
St. Paul's Rocks distant at noon, 568 miles. Made good 170 miles. Amount of 
current 20 miles, direction N. 75° W.
