" The next, and the highest forms of Entozoa, are the Ccelelmintha, 

 which on examination will be found analogous to the Annelida. 



" It is a remarkable circumstance, that looking on them collectively 

 as classes, the Crustacea and Annelida are the first in the animal 

 series possessing a truly dioecious mode of generation. So is it with 

 the analogues of these classes in the Entozoa, viz. the Acanthoce- 

 phala and Ccelelmintha, the only groups in the class which are truly 

 bisexual."
