As in the case of many other echinoderm genera inhabiting the north Pacific which as 
generic units are well circumscribed, the delimitation of the several species of Florometra presents 
extraordinary and unusual difficulties. Although the material at hand, consisting of about 1 500 
specimens from throughout the range of the genus, would be considered ample in the case of 
most types, in this case it merely increases the confusion.
