sound and trawl. Put trawl over. Sounded in 310 fathoms, but no trace of the bottom 
was obtained. Obtained serial temperatures at intervals of 10 fathoms down to 
200 fathoms. At 11 a.m. hove up trawl, which seemed to have fouled something at 
the bottom as it came up almost empty, containing only a portion of branching coral 
(Gorgonia), and a piece of black volcanic ash; on the iron was a trace of calcareous 
volcanic mud. Position of Station in strait between Molokai Island and Oahu Island. 
Proceeded for Honolulu, and at 2.20 p.m. anchored outside Honolulu Harbour in 
10 fathoms. At 3.20 p.m. weighed anchor and proceeded into harbour, anchoring at 
4 P.M, in 5 fathoms off the town of Honolulu. 
Surface Organisms. — The following species are recorded from the surface at this 
Station : — 
Rauiolaria (Haeckel, Zool, pt. 40). 
Acanthosphxra capillaris, Haeckel. 
Icosasj)is cruciata, Haeckel. 
Seihoconus trochus, Haeckel. 
Theopilium tricostatum, Haeckel. 
Theocampe cryptoprora, Haeckel. 
The tow-nets at the surface procured Glohigerina, Orhidina, and other ordinary 
oceanic organisms, and in addition large numbers of Cymhalopora [Tretomphalus) 
bnlloides. I’hey were of two different sizes, the smaller ones united into fours by a 
gelatinous substance. None of these specimens contained sarcode, similar to that found 
in pelagic Foramiuifera, but were filled with swarms of minute ciliated organisms, which 
crossed the field of the microscope with a rapid rotatory motion ; when one of the shells 
was crushed under a slide, a cloud of these organisms issued from the broken shell. 
When treated with carmine these little organisms showed a deeply- coloured spot at one end.

North Pacific, between Japan and the Sandwich Islands, the exact date not being 
noted : —
