E. Rathbun — List of the Brazilian JEehinoderms. 
149 
According to the generally accepted rules of nomenclature, the 
above name should give place to one of more modern date, and of 
such there is an abundance in the long list of synonymy arranged 
by M. Perrier. As, however, he is the authority for the consolida- 
tion of several of the species included in that list, and also for the 
determination of the only specimens that appear to be recorded 
from Brazil, I prefer to retain here the old name of Linck, which he 
has revived. Indian Ocean (Mull, and Tr.). China; West Coast of
