ASHWORTH, AN ACCOUNT OF ARENICOLA LO VENI KINBERG. 17 



The systematic position of A. loveni may be stated thus 

 — There is no affinity, beyond a generic one, between A. 

 loveni and A . claparedii, assimilis and glacialis. In its general 

 external appearance A. loveni most nearly resembles the large 

 Laminarian examples of A. marina but in its prostomium 

 and setae and in some of its interna] organs, especially its 

 septal pouches and statocysts, its departs markedly from A. 

 marina and much more nearly approaches A. cristata, from 

 which it differs chiefly in the number of its segments and 

 gills. These fäets indicate that the affinities of A. loveni lie 

 between A. marina and A. cristata but more closely to the 

 latter than to the former.
