The Comatulae (No. 1.) have their arms 
fringed on each side with a series of simple 
rays, and the under part of the body furnished 
with a tuft of simple indexed fibres, ending in 
an incurved hook, by which they attach them¬ 
selves to sea-weeds and other marine bodies. 
One species of Comatula is found on the 
English coast; the largest (Com. glacialis ) is 
from the Arctic Seas. The Fringed Comatula 
(Com.jimbriata) is from India. 
The Star-Fish ( Asterias ) Nos. 1. to 8. have 
the body depressed and more or less divided 
into rays, and the stomach furnished with only

several groupes, the first containing those which 
have a small orbicular body and long subcylin- 
drical arms, as the Medusa’s Heads (j Euryale'), 
which have the arms very long and repeatedly 
branched, so as to end in an immense multitude 
of small threads. In most of the species the 
arms are branched at the base, but in one ( Eu - 
ryale palmifera ), the base of the arms is simple, 
and the tip repeatedly forked.
