large size, some over two inches ia lengtli, Tomo2)tens, Cytherid, Copepods, mauy small 

 specimens of EiqjJiausia, Pteropods [Limacina ?), and Cranchia, a few specimens of 

 which were taken in every haul. 



On the night of December 27, 1873, oif Prince Edward Island, the tow-net procured 

 many Salpce, larvje of Euyliausia, Copepods, several specimens of Lepas on a piece of 

 pumice, many specimens of Hyperia and Gammarus, probably commensalistic and feeding 

 on the Salpw. 



In lat. 46" 46' S., the tow-net was sent down to 80 fathoms, and brought up Glohi- 

 genna, very much smaller than in the Atlantic, compound Radiolaria, many Smjittce, 

 small Copepods, a large species of Hyperia, Pteropods, and Cranchia. 



In lat. 46° 45' S. the water was quite red-coloured, due to innumerable red Copepods, 

 which were captured in so thick a mass that it was impossible to see the other animals ; 

 Sagitta, Hyperia, and other organisms were, however, present. The red colour of the 

 water, mentioned in the Indian Ocean Directory as occurring among the islands in these 

 latitudes, is probably due to these small Copepods. 



Off the Crozet Islands, January 3, 1874, a tow-net was sent down on the dredge rope, 

 and another was towed liehind the ship at a depth of aliout 80 fathoms, and yielded many 

 Diatoms and small Globigcri/ue, Sagitta, HahcypriK, Copepods, Hyiieria, Pteropods and 

 Pteropod larvse, and Salpce. 



Off Kerguelen, January 9 to 29, 1874, there were observed Medusae [Oceania), small 

 Planarians, small Tomopterid, Peltidium, Calanids and other Copepods, Gammartis and 

 another Amphipod, small Isopod, Zoe« (probablj' of the Brachyurous crab inhabiting the 

 pools) very small aud having just left the eggs. On the floating masses oi Macrocystt.s 

 were found Hydroids, Holothurians, small bivalve shells, Patella, and Polyzoa. Occasion- 

 ally the tow-net was completely filled with various species of Diatoms, at other times 

 with Amphipods (Hyperia) and numerous Copepods ; Pteropods (Limacina) were also at 

 times very al^undant. 



In lat. 52° 4' S., the tow-nets procured Ctenoplioraj, Sagitta, young Aphroditaceaus, 

 Copepods, Hyperia, and Eiq^hausia. At times the surface-net was full of living Diatoms, 

 in masses forming a yellowish slime, among which could be distinguished small Glohi- 

 gerime and Piadiolarians. When dragged at a depth of 100 fathoms, the tow-nets 

 produced similar results. 



In lat. 60° 52' S., the tow-nets procured Diatomacese, small Glohigeiince, Radiolaria 

 (including very fine specimens of Aulosphcera elegantissima, Haeckel), Cteuophorse, 

 Medusas, Diphyes, larvfe of Chirodota (?), Alciopa, Tomop)teris, Sagitta, Copepods 

 (Calanids), Hyperia, Prinino, Pteropods, and Ap)pendicularia. 



In lat. 65° 42' S. were observed Glohiyerina, Radiolaria, Diphye-^, Sagitta, Alciojm, 

 Annelid larvse, Cypridina, Primno, Clio, shell-less Pteropod, and the remains of a large 

 Cephalopod. 



During the afternoon of February 17tli, 1874, in lat. 65' 5' S., the sea was of a 

 greenish colour, and the water was found to be filled with many little spherical transparent
