In addition, the following are recorded in the note-hooks (March 9 and 10): — 
Foraminifera, Diphyes, Physophorid, Apolemia (?), Sagitta, Cypridina , Nauplii of a 
Cirriped ( Archizoea gigas , Dohrn), Hyperia, Phronima, with house and young, Primno 
■macropci, Euphausia, Sergestes . Zoeee, Atlanta, and Appendicidaria. 
Willemoes-Suhm writes : “ The warm-water animals were in greater number on the 
surface ; there were five specimens of Pyrosoma, nearly every one of which had eggs but 
no embryos. There was a Nauplius with a carapace like the cap of a Madeira peasant 
with many spines, 3 mm. in length ; it belongs to Euphausia , of which Metschnikoff 
has figured a similar larva ( Zeitschr . f. wiss. Zool., Bd. xxi. p. 396, pi. xxxiv., 1871), 
but not with such a striking form. There were many adult Euphausise on the surface. 
Phronima was taken with its house ; Claus has shown that the house is a young Pyrosoma 
in which Phronima establishes itself in order to feed on the Tunicata. He has found all 
stages, from the Pyrosoma just recently attacked by the Amphipod to those soft remains in 
which it has been taken by us. Preparations made by ns show that the tissues of these 
houses have the same histological structure as Pyrosomata when treated in the same manner. 
Sergestes , which we have not taken since leaving the Cape, was present at the surface. A 
little Amphipod, always taken on the surface during our Antarctic cruise, I find now to 
be Primno macropa, which was discovered by G u e r i n-Mene vill e near Chili, and which 
appears to be circumpolar. There were two beautifully transparent Cephalopoda 
apparently belonging to the genus Loligopsis .” 
Moseley writes : “ The surface fauna is changing ; on the night of the 9th the sea 
was full of Pyrosoma}, and the wake of the ship lighted up with them. Moreover, 
several pieces of Durvillea have been met with, and one piece covered with barnacles 
caught on the log ; hitherto the sea has been remarkably free from floating weed. This 
Durvillea probably came from St. Paul’s and Amsterdam Islands, since these islands lie 
in the direct course of the South Indian connecting current which, sweeping almost 
directly eastwards, joins tbe South Australian current. On the night of the 10th 
Pyrosoma was again abundant. On the evening of the 11th there were no Pyrosomse 
at the surface, but a slight scintillating phosphorescence from the Copepods, and I saw 
a piece of Durvillea float past. Phronima, while in its house with its young, moves 
the whole about by protruding its tail from the end and working it.”
