II. Asteroidea 



by 

 I. LIEBERKIND. 



The collection of sea-stars does not offer anything of particular interest, 

 and as only some of the species of Asteroidea known to occur at the islands 

 are represented, I shall have to be content to briefly discuss the systematics 

 of the collected forms, and, as far as possible, to give a complete list of the 

 literature concerning the specimens. 



The material contains the following species: 



Asterina calcarata (Val.) Perr. - . 



Op India ster Agassizii Ed. Perr. 



Asterias fernandcnsis Meiss. 



Cosmasterias sp. 



I. Asterina calcarata (Val.) Perrier. 

 (Syn. Asterina calcarata var. selkirki Meissner.)
