OF THE KERGUELEN REGION OF THE GREAT SOUTHERN OCEAN. 443 



LIST V. 



Metazoa recorded from the Kerguelen Region, from Sources other than the 



Challenger Expedition. 



In order to complete our survey of the marine fauna of the Kerguelen Eegion we give 

 here a list of species recorded from other sources 1 (British and American Transit of Venus 

 Expeditions, "Gazelle" Expedition, &c), excluding a number of unnamed species, the 

 distribution of which cannot be discussed, as well as land and fresh-water species. Species 

 already recorded in the preceding Challenger list (List IV.) are not repeated in this list, 

 and where the nomenclature does not agree that adopted in the Challenger Report is 

 indicated in square brackets.

2 Of the Sponges collected at Kerguelen by the British Transit of Venus Expedition, H. J. Carter writes : — The 

 collection of Sponges from Kerguelen Island is very limited in extent. So far as it goes, it may be said to present a 

 European, and more especially a British facies. Half of the species at the fewest, may be picked up at any time on 

 the beach of South Devon : — viz., Isodictya rosea, Halichondria plumosa, H. caniosa, and H. semguinea. To these we 

 might add a fifth species, H. panicca, for the Kerguelen variety differs from the normal British form only in the 

 possession of spicules twice the size of the latter. Of the three species remaining Thalysias is common to the Mediter- 

 ranean and the seas between the Americas ; the Ute occurs on the N.W. coast of Spain and in the Mediterranean ; 

 and one only, the Tethya, is decidedly antarctic. This last was the only specimen obtained from a considerable depth ; 

 all of the others were either collected with the grapple within the Laminarian zone, or were the produce of shore- 

 collecting between tide-marks or amidst the refuse of the beach. Probably more extended research would have brought 

 to light divers of the many peculiar forms which abound in the Cape seas and in those of the southern part of 

 Australia. In the course of my examination I have met with very few Foraminifera, no Globigerina, and no coccoliths. — 

 (Phil. Trans., vol. 168, p. 286.) 



Carter refers some Sponges collected at Kerguelen by the British Transit of Venus Expedition to the species 

 Thalysias subtriangularis, Duchassaing and Michelotti, and Tethya antarctica, Carter. Ridley and Dendy refer 

 the first to their Petrosia similis, regarding it as distinct from the West Indian Petrosia subtriangularis, while 

 Sollas refers the second to his Tetilla grandis, regarding it as distinct from Tetilla antarctica obtained by Ross' 

 Antarctic Expedition in 206 and 300 fathoms in the neighbourhood of Victoria Land.
