 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 Polychaete 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. 



V. Lagisca magellanica M'Intosh, Challenger, Vol. 

 XIL, p. 82. Habitat : Strait of Magellan, 

 175 fath. Kerguelen, 127 fath. 

 The genus appears to belong to the southern hemi- 

 sphere, being widely distributed in that region, and in the 

 tropics. It occurs also in the northern hemisphere, but 

 is rare. 



There were also present in the collection some frag- 

 mentary specimens belonging to the genera Terebella 

 and Cirratidus, but they were too badly preserved for 

 identification.
