Though the above-described specimens differ from Eri/lhrdiiirlrn, 

 rubra by having almost smooth arm-bases and proximal pinnules, 1 

 have referred them to this species, as the other characteristics coin- 

 cide, and considered the differences to be ascribable to different ages 

 in my specimens and those described of A. II. Claek. 



A. H. Clark originally called the species Aniedon ruher. When 

 a little later he created his new classification of the Comatulids and
