I am not quite sure that the small colonies examined really 

 belong to A. Mytili. They agree, indeed, with the colonies of this 

 species in the form and position of the single zooecia, the distal end 

 of which is only very little projecting, but in opposition to w^hat is 

 the case in other colonies of A. Mytili the zooecia are very opaque.
