12 Pratt, PolycluEtafrom the Falkland Islands. 



Genus. Pacific (Double Island), Madeira, Eastern 

 coast of United States, Australia (Sydney), Britain, 

 Mediterranean, English Channel. The genus has been 

 taken in fairly cool and warm waters of both northern and 

 southern hemispheres, but not in tropical waters. 



As this species has been found in water-logged timber, 

 it is possible that its wide distribution has been brought 

 about by the agency of man. This, however, cannot 

 account for the fact of the genus, which contains many 

 sand-dwelling species, being extra-tropical. 



ARENICOLID.-E. 



Arenicola claparedii. Levinsen, Gamble, and Ash- 

 worth (:oo). 



A few postlarval forms found swimming on the surface 

 of the sea. Not taken in tow-net gatherings in Stanley 

 Harbour. 



This species has been identified by Dr. J. H. Ashworth, 

 of Edinburgh. 



Distribution. — Naples, California (Crescent City, 41° 

 44' N.). New to Falkland Islands, and to Southern Hemi- 

 sphere. The distribution of this form is interesting in 

 that it has been taken in fairly warm water of both 

 northern and southern hemispheres, but not in the tropics. 



The genus appears to be cosmopolitan. 



CiRRATULID/E. 



Promenia jucunda. Kinberg ('65), p. 254, Ehlers 

 ('g6), p. 113. 



One specimen taken on the shore at low water. 



Distribution.— Sts. Magellan. New to Falkland 

 Islands. 



The genus appears to be exclusively e.xtra-tropical.
