Of the new species three are from the Galapagos Islands; the

 young of Ophiocoma pumila, is from the West Indies. 



Dr. Hubert Lyman Clark has been so kind as to give me his opinion 

 on the status of Hesperocidaris houstoniana and the three species of 

 Ophiocomella, and Prof. Walter K. Fisher was so good as to examine 

 the specimen listed as Sclerasterias, sp.
