Peculiar to Falklands. Soled ad Bay (Lesson). Stanley 



Harbour. 



The genus (after allowing for Haeckel's weeding out of synonyms) is 



curious in its distribution, in that the species H. macloviana is the only 



representative in southern seas, and even this has, as yet, only been 



recorded from the Falkland Islands. The other members of this genus 



are fonnd in the temporate and cold regions of the northern hemisphere 



as well as in the north tropical zone. 



Porifera. 



In the collection are two species of the genus Sycon : — 



Sycon ciliatum Fleming. Habitat: Europe. New to Falklands. 

 Sycon ramsayi Lendenf. Habitat: Australia. New to Falklands. 

 One small specimen. 



The genus is cosmopolitan in shallow to moderately deep 

 water. 



Polyoh^ta. 



Nereidiformia. 



I. Nereis eawni MTntosh, Challenger, Vol. XII., p. 223. 

 Habitat : East of South America. Fernando Noronhia, 

 25 fath. Marion Island, 69 fath. Kerguelen, 20 fath. 

 Falklands, 5—10 fath. 

 II. Nereis patagonica M'Intosh, Challenger, Vol. XII., p. 228. 

 Habitat : East of Strait of Magellan. New to Falklands. 

 III. ISereis herguelensis Baird ?, Challenger, Vol. XII., p. 225. 



Habitat : Kerguelen New to Falklands. 

 IV. Nereis atlantica M'Intosh, Challenger, Vol. XII., p. 219. 

 Habitat : Cape Verde Islands. New to Falklands. 

 The genus is widely distributed in north and south temperate and 

 tropical seas, from very shallow to very deep water (1,520 fath). 



The Polychsete species represented in the collection from the Falkland 

 Islands appear to be peculiar to the southern temperate zone, although 

 most of the genera are widely distributed in the north and south 

 temperate and cold seas, as well as in the tropics.
