In addition, the following are recorded in the note-books from the tow-nets, two 
of which were sent down to 200 fathoms : — Peridinium, Glohigerina, Hastigerina, 
Pidvinidina, large Medusae {Pelagia), Sagitta, Alciopa, Tomopteris, Cypridina, 
Saphirina, Copilia, Hyperids, larvae of Euphausia' ond. other Decapods, Lucifer, small 
shells, Atlanta, Pteropods (naked and shelled) and larvae. Appendicular ia, Doliolum, 
and small Scopelids with phosphorescent dots and brilliant scales. The Medusae gave 
off phosphorescence when touched, apparently from all parts of the body, and the eyes 
of the Euphausi^ became very brilliantly phosphorescent now and then and also when 
agitated. The specimens of Pulvinulina micheliniana were very numerous, and the 
shells were surrounded by a yellowish-green coloured mass of granular protoplasm. The 
protnphismic matter within the shell coloured deeply with carmine. Mixed with the 
protoplasm surrounding the shells were numerous Coccospheres, Rhabdospheres, and 
Diatoms.
