characteristics. These specimens are identical with those Hsted as vepratica 

 by Koehler (1914, Bull. 84 U. S. N. M., p. 94) but are not the same as the Pacific 

 species, nor are they similar to the two ophiurans from the Tortugas here 

 described. They are further discussed, under the name metallacta (g. v.). While 

 the three species are no doubt nearly related, in the present state of our 

 knowledge, it is important that they should not be confused with each other.
