Distance at noon from east point of Oahu Island, 133 miles. Made good 98 miles. 
Amount of current 10 miles, direction S. 73° W. 
Surface Organisms. — The following species is recorded from tow-net sent down to 
1000 fathoms at this Station : — 
Fishes (Gunther, Zool. pt. 78). 
Branchiostoma 'pelagicum, n.sp. 
The tow-nets at the surface procured the usual organisms, including many Glohigerinas 
with long spines. ’ Four nets were sent down to 1000 fathoms, and brought up : Diatoms, 
Pyrocystis (two forms), Peridinium, Oscillatoriacese, Hastigerina, Pulvirndina, larvae of 
Chirodota and Balanoglossus, Annelids, Cypridina, Saphirina and other Copepods, 
Phronimids, Euphausia, Sergestes, Salpa, Appendicularia, Amphioxus and several 
small fishes. Many of the specimens of Pyrocystis were again noticed to be in a state 
of division ; the outer surfaces of the spheres were covered with little pellucid dots which 
coloured deeply with carmine.
