OF THE KERGUELEN REGION OF THE GREAT SOUTHERN OCEAN. 479 



large size, some over two inches in length, Tomopteris, Cytherid, Copepods, many small 

 specimens of Euphausia, Pteropods (Limacina ?), and Cranchia, a few specimens of 

 which were taken in every haul. 



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

 many Salpce, larvse of Euphausia, Copepods, several specimens of Lepas on a piece of 

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

 on the Salpce. 



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

 gerina, very much smaller than in the Atlantic, compound Radiolaria, many Sagittce, 

 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 behind the ship at a depth of about 80 fathoms, and yielded many 

 Diatoms and small Globigerince, Sagitta, Halocypris, Copepods, Hyperia, Pteropods and 

 Pteropod larvae, and Salpce. 



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

 Planarians, small Tomopterid, Peltidium, Oalanids and other Copepods, Gammarus and 

 another Amphipod, small Isopod, Zoese (probably of the Brachyurous crab inhabiting the 

 pools) very small and having just left the eggs. On the floating masses of Macrocystis 

 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 abundant. 



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

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

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

 gerince and Radiolarians. 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 Globigerince, Radiolaria 

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

 Medusas, Diphyes, larvse of Chirodota (?), Alciopa, Tomopteris, Sagitta, Copepods 

 (Calanids), Hyperia, Primno, Pteropods, and Appendicularia. 



In lat. 65° 42' S. were observed Globigerina, Radiolaria, Diphyes, Sagitta, Alciopa, 

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

 Cephalopod. 



During the afternoon of February 17th, 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
