This is a peculiar organism, resembling a mass 

 of Astrorlilza-Vike tubes arranged radially. When 

 broken open the separate tubes are seen to bear 

 numerous apertures opening into the interstices of 

 the mass. The examples on which the description 

 is based were obtained from the ' Triton ' dredgings 

 in the Faroe Channel by Murray. The specimens 

 measure about 1\ inch (38 mm.) in diameter.
