60 CLASSIFICATIONS OF ZOOPHYTES. 



ment, and even his latest systematical attempt exhibits many de- 

 relictions of them. Having, at the suggestion of Pallas, establish- 

 ed a section of avertebrated animals for the reception of such as 

 exhibited in the disposition of their organs a radiated appearance, 

 to the whole of which he applied the term Zoophytes, he sub- 

 divided it into five classes, of which the last but one embraced 

 the subjects of the present treatise. They were named Polypes 

 because, from the tentacula encircling their mouth, they some- 

 what resembled the cuttle-fish called Polypus by the ancients ; 

 and they were defined to be little gelatinous animals the mouth 

 of which, encircled with the tentacula, lead into a stomach some- 

 times simple and sometimes furnished with intestines in the form 

 of vessels. It is in this class that we find those innumerable com- 

 pound animals, with a fixed and solid stem, which were so long re- 

 garded as marine plants. The following is a synopsis of Cuvier's 

 method, as it appears in the last edition of the " Regne Animal."*
