IS fleshy, and the polyps open out on its surface 

 like a star with six or eight rays [asteroid means 

 " star-shaped."] 



3. Helianthoids. The polyps are single, and at- 

 tached temporarily or permanently to their dwelling- 

 places in the rocks. Some few being " free," and 

 some — e.g. corals, surrounded with a crust of hard 

 lime — their tentacles (or arms) open out in a circular 

 shape, like the rays of the sun [helianthoid means 

 " sunflower- shaped."] 



Now a sea-anemone is a Helianthoid, or sunflower- 

 shaped polyp, and all Helianthoids are very near 

 relations of our anemone. Let us, then, pause here, 

 and draw up a brief catalogue or table of the divi- 

 sions about which we have been talking, and we 

 ought to get a very clear notion into our heads of 

 the form and character of our friend. 



^ All Natural Objects are divided into 



* Organized and Unorganized Bodies. 



e.g. man, beasts, trees. e.g. stones, lead, iron. 



[Bodies possessing, or not possessing, the means of adding to 

 their own growtli by their own implanted powers, exercised by 

 definite portions of their bodies called organs.] 



* The following Table is based on general laws, to all of which 

 there are exceptions. The principles of classification are now 

 undergoing investigation, and the present system may not be 

 regarded as perfect or permanent.
