Il. 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. 
Ophidiaster Agassiz Ed. Perr. 
Asterias fernandensis Meiss. 
Cosmasterias sp. 
1. Asterina calcarata (Val.) Perrier. 
(Syn. Asterina calcarata var. selkirki Meissner.)
