ments will have a disturbing influence on its essentially loosely connected organism. How- 

 ever carefully therefore I have acted in endeavoring to lift up this gem of the ocean, I 

 have never succeeded in obtaining it entire. On the slightest touch, all the arms usually 

 break off at their junction with the disc; so that the latter is most frequently quite de- 

 tached from them. Only in a very few instances, by employing the utmost care, and by 

 placing the specimen immediately in spirit, I have been able to obtain one or more arms 

 in natural connexion with the disc. I have thus, as a great rarity, got one single young 

 specimen preserved, with 4 arms attached to the disc. This is the specimen from which 

 the 3 first figures in Tab. I have been delineated.
