crabs. Tlic crabs, a small 6^?-rtps?/s-like form and another larger one, inhabit the logs as 
does Nmitilogmpsus those in the Atlantic. These various animals appear to frequent 
the logs because of the concentration about them of the surface animals. Enormous 
quantities of small fish were about the wood, and troops of dolphins {Coryphsena), and 
sharks {Carcharias) two to four feet in length, were seen feeding in the midst of the 
driftwood masses, splashing the water and showing above the surface as they caught 
their prey. I found a large Ctenophor {Eucharis) and Physalia, and very small flying 
fish were common, as among the gulf- weed. The wood was bored by a Pholas and 
by an Ajjhroclita” 
The Challenger remained at Humboldt Bay, New Guinea, on February 23 and 24, 1875 
(for description of Humboldt Bay see Narr. Chall. Exp., vol. i. pp. 681-689). The 
deposit in 37 fathoms was a Blue Mud, containing 28’91 per cent, of carbonate of lime, 
in which the following species of Ostracoda were observed : — 
().STR.\coDA (Brady, Zool. pt. 3).

Wellington Harbour, N.Z.
