232 Boyal Society : — 



dredging was in 1900 fathoms, 125 miles to the south-westward 

 of Cape Agulhas ; it was not very successful. 



Marion Island was visited for a few hours, and a considerable 

 collection of plants, including nine flowering species, was made by 

 Mr. Moseley. These, along with collections from Kerguelen Island 

 and from Yong Island, of the Heard group, are sent home with 

 Mr. Moseley's notes, for Dr. Hooker's information. 



A shallow-water dredging near Marion Island gave a large 

 number of species, again representing many of the northern types, 

 but with a mixture of southern forms, such as many of the cha- 

 racteristic southern Bryozoa and the curious genus Scrolls among 

 Crustaceans. Off Prince Edwards Island, the dredge brought up 

 many large and striking specimens of one or two species of Al- 

 cyonarian zoophytes, allied to Mopsea and Isis. 



The trawl was put down in 1375 fathoms on the 29th December, 

 and in 1600 fathoms on the 30th, between Prince Edward's Island 

 and the Crozets. The number of species taken in these two hauls 

 was very large ; many of them belonged to especially interesting 

 genera ; and many were new to science. I may mention that there 

 occurred, with others, the well-known genera Euplectella, Hyalonema, 

 Umbellularia, and Flabellum, two entirely new genera of stalked 

 Crinoids belonging to the Apiocrinidse, Pourtalesia, several Spa- 

 tangoids new to science (allied to the extinct genus Ananchytes), 

 Salenia, several remarkable Crustaceans, and a few fish. 



We were unfortunately unable to land on Possession Island on 

 account of the weather ; but we dredged in 210 fathoms and 550 

 fathoms, about 18 mdes to the S.W. of the island, with a satis- 

 factory result. We reached Kerguelen Island on the 7th of 

 January, and remained there until the 1st of February. During 

 that time Dr. v. Willemoes-Suhm was chiefly occupied in working 

 out the land-fauna, Mr. Moseley collected the plants, Mr. Buchanan 

 made observations on the geology of those parts of the island which 

 we visited, and Mr. Murray and I carried on the shallow-water 

 di'edging in the steam-pinnace. Many observations were made, 

 and large collections were stored in the different departments. We 

 detected at Kerguelen Island some peculiarities in the reproduction 

 of several groups of marine invertebrates, and particularly in the 

 Echinodermata, which I have briefly described in a separate paper. 

 Two days before leaving Kerguelen Island, we trawled off the 

 entrance of Christmas Harbour ; and the trawl-net came up, on one 

 occasion, nearly filled with large cup-sponges belonging to the 

 genus Eossella of Carter, and probably the species dredged by Sir 

 James Clark Boss near the ice-barrier, Eossella antarctica. 



On the 2nd of February we dredged in 1 50 fathoms, 140 miles 

 south of Kerguelen, and on the 7th of February off Yong Island, in 

 both cases with success. 



We reached Corinthian Bay, in Tong Island, on the evening of 

 the 6th, and had made all arrangements for examining it, as far 

 as possible, on the following day ; but, to our great disappointment, 

 a sudden change of weather obliged us to put to sea. Fortunately
