ST. HELENA. 
Oeder Crinoidea (or Feather-stars). 
Comatula, Lamck. 
C. sp. ? This very pretty, purple, feathery creature, not unlike 
the head of a miniature palm-tree, is occasionally taken from the 
pools of sea-water on the West rocks, and other parts of the coast. 
I found one specimen at Lemon Valley, but it is extremely rare. 
VI. INFUSOKIA. 
CLASS I.— INFUSORIA. 
Under this head, search has yet to be made at St. Helena. 
VII. PEOTOZOA. 
CLASS I.— SPONGIDA. 
There is a small brown Sponge, seen growing in the pools of sea- 
water on the coast, which does not attain to any size. Pieces of 
it as large as a cricket-ball are frequently picked up on the sea 
beaches. Through the kindness of Professor Dickie, it has been 
examined by Dr. Bowerbank, who says "it belongs to the o- en us 
Halispongia of De Blainville. The characters are the same as those 
of the coarse sponges of commerce from the West Indies.”
