The distribution of the genus will probably be much extended 

 when the sponges of some extensive coasts are examined for barn- 

 acles — such as east and west Africa and west America. Most of the 

 species now known inhabit the shores and archipelagos between 

 Japan and South Australia, with the most intense speciation about 

 the middle of this region.
