At 6.45 a.m. shortened and furled sails, and got up steam to sound. At 7.30 A.M. 
sounded in 2475 fathoms. At 9 a.m. took a series of temperatures down to 500 fathoms. 
At 10.15 a.m. completed observations, and made all plain sail. 
St. Paul’s Rocks distant at noon, 7 38 miles. Made good 145 miles. Amount of 
current 23 miles, direction N. 38° W. 
Surface Organisms. — The following species are recorded from the surface-net sent 
down to 100 fathoms : — 
Amphipoda (Stebbing, Zool. pt. 67). Macrura (Spence Bate, Zool. pt. 52). 
Phronima pacijica, Streets. Sergestes oculatus, Kroyer. 
During the day the tow-net was sent down to a depth of from 80 to 100 fathoms, 
and, though it could only have been at that depth for a short time, a great many 
animals were obtained which were not to be found in the surface water. There was a 
great abundance of Globigerinse , a few Pulvinulinse, many species of Radiolaria, 
Peridinium, small Medusa, Sagitta, Ilydrophanes (for the first time), Saphirina and 
other Copepods, Hyperia, Pterotrachea , Pteropods, Cranchia, young Pyrosoma, 
Appendicularia, FritiUaria , Doliolum. 
Wiilemoes-Suhm writes: “From a depth of 100 fathoms the tow-net, after having 
been out only a verj* short time, brought up a quantity of those animals taken at the 
surface only at night, while the tow-net dragged’ at the surface for a considerable time 
brought in very little. This shows clearly that certain animals live during the day at a 
depth of 100 fathoms, and come to the surface only at night. Other forms, however, not 
taken to-day, but which have been ta,ken in abundance at night, must live during the day 
probably at still greater depths. Among the worms was a very transparent Ilydrophanes, 
hitherto observed only a few times by Krohn and Claparede ; the latter has given an 
excellent figure of the Mediterranean species, Ilydrophanes krohnii, from which the species 
taken to-day differs somewhat in the form of the bristles of the antennae, is somewhat 
older, and is possibly only a variety or the opposite sex. The worm is interesting as 
being a connecting link between the Phyllodoceans and the Alciopeans ; it is an Alciopa 
with simple eyes, or one might say that Alciopa is only a Phyllodoce with very big eyes, 
and that it is quite unnatural to make a separate family for it. Anyhow it is very 
interesting to find a Phyllodoce with ordinary eyes deviating from all the other bottom- 
living members of the family in the extreme transparency of its tissues and glands at 
the base of the feet. The genus Ilydrophanes is besides distinguished by immense 
bacilliparous glands opening, as I have found to-day, into the pharynx, and by two ciliatory 
sacs on each side of the head, which can be inverted and then look like ciliated tentacles. 
Such retractile ciliated organs are known in several Annelids, and I have recently shown 
their presence in Glycera alba. They may perhaps be compared physiologically with
