Notes. — In spite of the close agreement in the form of the arm plates 

 and the plates of the oral surface, and in the number of arms, with the 

 species of Ophiocomella^ this little species should be referred to 

 OphioTnastix^ with which it agrees in the relations of its arm spines 

 and in the general scheme of its color pattern. It does not agree with 

 any of the known species of Ophiomastix^ none of which are six-rayed 

 in any stage. The color pattern also is unique.
