Variation : 



Colour varies form darker to lighter brownish, — As in A, virginea, specimens 

 of A. rubella, living on coral bottoms at Iceland and Finmark have a concave under- 

 side and sometimes an elevated shape (var, elevata Odhner 1910); but stages of 

 transition from such extreme forms lead over into the type.
