Retepora, and another Polyzoon spreading over Pinna and other sheds, were present, 
along with compound Ascidians. Crabs, Alpheus (mostly in Sponges), and small 
GaJathefe were eommon. There were also many shells, especially Murex and Pecten, 
the latter very large and fine.” 
The stomachs of the Ilolothurians contained a greenish mass composed of pieces of 
broken shells. Echini spines, and many varieties of shallow-water Foraminifera. 
The Challenger remained at Zebu from 1.30 p.m. on January 18 till 4 p.m. on 
January 24, 1875. During this time dredgings were taken from the steam pinnace and 
from the ship on the Eup>lecteUa-gxo\m(\. in 85 and 95 fathoms (see Station 209). 
Surface Organisms. — While at anchor at Zebu the tow-net procured : — Diatoms, 
two shore forms of Foraminifera, small Acanthometrje, Medusae, Diphyes, Ctenophorae, 
Tomoptcris, Copepods, Amphipods, larval Lamellibranchs and Gasteropods, and 
A piiendiculana.

Temperature of air at noon, 81°'3 ; mean for the day, 79°‘3. 
Temperature of water at surface, 81°‘0 ; bottom, 71°‘0. 
Depth, 95 fathoms ; deposit. Blue Mud, containing 35’82 per cent, of carbonate

At 7 A.M. got up steam. At 9 a.m. weighed anchor and proceeded out of Zebu Harbour

of channel between Zebu and IMactan Islands, on the Eup>lectdla-gTO\md. In the course 
of the day the big dredge was lowered five or six times in depths varying from 95 to 
100 fathoms, many specimens being obtained. At 3 p.m. completed dredging, and at 
4.15 P..M. returned to the anchorage in Zebu Harbour.
