P. H. Carpenter's collection includes numerous specimens of this species, from 0"2 mm. 

 in length to fully grown forms. They were obtained partly from Antedon petasus, D. 

 and K. sp. (Cattegat), partly from Antedon rosacea (from Torquay, Arran, Oban, Isle of 

 Man, Keumaes Bay, north coast of Anglesea). Those from the last two localities were 

 dredged by the Liverpool Marine Biological Committee, and among them there is one 

 form with a supernumerary cirrus between the seventh and eighth left cirri, and another 

 which is remarkable because of its all but perfect circular contour (longitudinal diameter 

 1'52 mm., transverse 1'5 mm.).
