stages, from the Pyrosoma just recently attacked by the AmiDhipod to those soft remains 

 in which it has been taken by us. Preparations made by us show that the tissues of 

 these houses have the same histoloo;ical structure as Pvrosomata when treated in the same 

 manner. S&rgestes, which we have not taken since leaving the Cape, is 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 GuiiIRIN-Menevlile near Chili, 

 and which appears to be circumpolar. There were two beautifully transparent Cephalo- 

 poda apparent!)^ belonging to the genus Loligojjsis." 



MosELEY writes : — " The surface fauna is changino' ; on the night of the 9th March the 

 sea was full of Pyrosomce, and the wake of the ship was lighted up with them. Moreover 

 this morning several pieces of Durvillea were met with, and one piece covered witli 

 barua'cles caught on the log ; hitherto the sea has been remarkably free from floating weed. 

 This Dw-villea probably comes 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 the South Australian current. On the night of the 10th March 

 Pyrosoma was again abundant. On the evening of the 11th March there were no 

 PyrosomcB 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."
