50 BULLETIN OF THE 
many specimens of Doliolum, but the same types of Crustacea, Copepods, 
Macrurans, and Siphonophores, the same species of fishes, with a differ- 
ent larval Plagusia from that of the former haul, characterized by a dark 
violet black longitudinal band along the Hanks, and a young Octopus. 
Immediately after the above trial, at the same station (Hy. Station 
3619, depth 1,100 fathoms), we sent down the Tanner net to tow at a 
depth of 1,000 fathoms, to endeavor to ascertain what might be obtained 
by towing as nearly as possible about 100 fathoms above the bottom. 
We let out 1,160 fathoms of wire rope, and towed for nearly sixteen 
minutes; the extra length of rope was then slowly wound in to bring it 
vertical, and the messenger was sent down to trip the crank ; the time 
of the messenger in reaching the detacher was seven minutes and thirty- 
five seconds ; the Tanner net was then hauled up at the usual rate of 
four minutes per 100 fathoms, and the customary precautions used in 
examining the contents of the upper (open) and lower (closed) parts of 
the net. A sounding was taken immediately after the net came to the 
surface, and we found that during the time we trawled and towed we 
had drifted into a depth of 1,482 fathoms, so that we failed in the im- 
mediate object of our trial. We found in the closed net a large violet 
Amphipod, and a brilliant carmine shrimp, of the usual color of the 
deep-sea Macrurans. These two specimens must have come from a belt 
of not more than 350 fathoms above the bottom, and were different 
from anything we had collected before. The open part of the bag con- 
taiped an Atolla, a fine specimen of the pink Stomobrachium, both prob- 
ably from a comparatively moderate depth, judging from their perfect 
state of preservation. The same Crustacea and fishes came up as on 
other trials in that part of the Tanner net, and also a fine orange Am- 
phipod like one brought up in the trawl at Station 3383, and assumed 
then to come from a depth of 1,832 fathoms. The open net also con- 
tained a buge Noctiluca, measuring about half an inch in diameter, with 
a peduncle fully ten times the diameter of the disk. 
On the 25th of March, at a point not quite half-way between Cape 
San Francisco and the Galapagos, Hy. Station 2627, the depth being 
1,832 fathoms, the Tanner net was sent to tow at a depth intended 
to be about 100 fathoms above the bottom, and which varied from 
1,773 fathoms to 1,739. Within these limits the net was towed for 
twenty minutes, the same precautions being taken to bring the wire 
rope gradually vertical before the messenger was sent down to close 
the net; the messenger was seven minutes in reaching the detacher. 
The net was then hauled up, and the contents of the lower part, which
