Surface Organisms. — The following species are recorded from the surface at this 
Station : — 
Pteropoda (Pelseneer, Zool. pt. 65). 
Clio ( Creseis ) acicula (Rang). 
Amphipoda (Stebbing, Zool. pt. 67). 
Phorcorrhaphis zamboangze, n.sp. 
Willemoes-Suhm writes : “ In the morning some surface things were brought to me, 
among which I found some Diphyes, an Amphipod of probably unknown genus, many 
small Schizopods, Styliola, and many of those small bicornous Salpse, besides the Zoese 
and ever-present Sagitta. There was also a Salpa presenting a peculiarity in the lilac 
glands of the digestive cavity ; these glands showed interruptions due either to want of 
secretion, which is not very likely, or to separation into several.” 
Station 82 (Sounding 146), Azores to Madeira (see Chart 6 and Diagram 3).

Depth, 2400 fathoms; deposit, Globigerina Ooze, containing 7979 per cent, of 
carbonate of lime (see Murray and Renard, Deep-Sea Deposits Chall. Exp.). 
At 8.30 a.m. got up steam, and at 9.15 a.m. shortened and furled sails. 
At 10.30 a.m. sounded in 2400 fathoms. Took serial temperatures down to 1500 
fathoms. Made current observations, and found surface current running south at the 
rate of a quartei of a mile per hour. At 3 p.m. completed observations, and made all 
plain sail. At 7.30 p.m. shortened and furled square sails, and got up steam. At 
7.40 p.m. proceeded under steam. 
Distance at noon from Pt. Fargo, Madeira, 116 miles. Made good 54 miles. Amount
