In addition, the following are recorded in the note-books (April 5 to 8) : — 
Oscillatoriacese, Noctiluca, Ethmodiscus, Coscinodiscus, many small Diatoms in chains, 
Vorticella on Bacteriastrum, Peridinium (two species), Pyrocystis (two varieties), 
Glohigerina, Orhulina, Hastigerina, Pidvimdina, Acanthometrae, Polycystinae (some 
very fine specimens from tow-net sent down to 400 fathoms), Collosphaeridse, Medusae, 
Velella, Porpita, Ctenophorae, Echinoderm larvae, Sagitta, Alciopa, Tomopteris, 
Sipunculid and other larvae, curious Annelid (from tow-net sent down to 400 fathoms), 
Cypridina (several species), Calanus, Saphirina, and other Copepods, Hyperids, 
Phronima, Oxycephalus, Euphausia and larvae, Lucifer, Phyllosoma, Sergestes larvae, 
small crab, small Lamellibranchs, Ethella, Atlanta, Carinaria, Pteropod larvae, 
Appendicularia (two varieties), Doliolum, larval Amphioxus and Scopelids with 
phosphorescent spots. A male shark [Carcharias glaucus), eight feet in length, was 
caught ; it had four pilot fish about it. Mr Murray was away in a boat examining the 
surface with a water-glass. The water was very clear ; only Oscillatoriaceae, small 
Crustacea, Radiolaria, and long strings of Diatoms could be observed. Whales were 
seen spouting near the ship on the evening of the 6th, The presence of Noctiluca, 
larval Amphioxus, Echinoderm and Annelid larvae, numerous small Diatoms, and 
Infusoria, indicated the presence of brackish water, probably carried from the coast of 
Asia by the Japan current.
