ECHINOIDEA. :i. 



Prospatangtis\ the name Schizastcr is retaiiied for the rest of the species of this groiip. Further 

 Echinocardium is restored for (Moira) airopos. — I may refer to iiiy remarks above, ]3. 132, regarding 

 these unfortunate changes. 



It is, indeed, quite discouraging witli all the changes of the generic names, and it seems im- 

 possible to reach an arrangement which can be unanimously accepted. I think there is only one way 

 to get out of this alniost insupportable condition of the nomenclature, viz. if all the Echinologists of 

 the present time meet to form an international committee and come to an agreement regarding all 

 the names of Echinoidea, one by one, and then pnblish a complete list of all the names finally adopted, 

 with their synonyms and complete history. From the date of publication of such a list the endless and 

 annoying discnssions and the perplexing changes would cease — they will scarcely cease before. Per- 

 haps it would be necessary to do so also for other difficult groups; for a first trial the Echini would 

 be an excellent group, as the number of species and names is not so exceedingly great.
