THE VOYAGE OF H.M.S. CHALLENGER. 
Statio.n *254. 
Organisms from 
Si'rfack-Xets. 
2 5 ‘4 milligrammes per litre. At 1 p.m. commenced heaving in trawl, but at 3 p.m. 
the trawl-rope carried away, the trawl with three tow-nets and a few thousand fathoms 
of rope being lost. A manganese nodule was procured in the water-bottle. At 3.20 p.m. 
made sail. Albatrosses still followed the ship. 
Honolulu distant at noon, 852 miles. Made good 150 miles. Amount of current 
3:^ miles, direction S. 28° W. 
Surface Organisms. — The following species ^re recorded from the surface at this 
Station : — 
R.\diolaria (Haeckel, Zool. pt. 40). 
Cenosphsera cristata, Haeckel. 
Octodendron spirale, Haeckel. 
Heliodi'ymus setosus, Haeckel. 
Acanthonia quadrifolia, Haeckel. 
Xiphacantha macroptera, Haeckel. 
Tessaraspis hexagonalis, Haeckel.

Sethoconus trochus, Haeckel. 
Theocainpe ci'yptoprora, Haeckel. 
CiLstanella ivyvillei, Haeckel. 
Coelodendrum hifurcum, Haeckel. 
In addition, the following are recorded in the note-books : — Pyrocystis (two forms), 
Peridinium {in catena), Ethmodiscus, Rhizosolenia, and Diatoms attached to Copepods 
Coccospheres and Rhabdospheres abundant on the surface, Glohigerina, Orhulina, 
Ilastigerina, Pulvinulina menardii and Pulvinulina micheliniana, I'intinnus and other 
Infu.soria, Medusa3, Velella, Sagitta, Alciopa, Tomoptcris, Distomum, Cypridina, 
Cojnlia and other Copepods, Zoese of Lepas fasciculans, Hyperids, Eup>hausia with 
Zrieae and larvte, Atlanta, Oxygyrus, Tiedemannia\_ = Gleha], Apypendicularia, Fntillaria, 
holiolum. A haul from over 100 fathoms brought up a few Challengeridae and other 
Radiolaria. There were again a good many small pieces of pumice covered with mould or 
Algae, and some seeds which did not seem to have come from the ship. Several specimens 
of Pyrocystis noctiluca were observed to be in process of division, two distinct 
individuals being surrounded by a common chitinous membrane. Some of the specimens 
of Orhulina had verj’ thin shells, and the Glohigei'inse inside, attached to the inner 
surfaces of the Orhulinse by long spines could be seen with great distinctness.
