CHAPTER XXXIV OTHER UNSEGMENTED WORMS From the time of Linnaeus in 1758 until the end of the last century a diverse group called Vermes, or worms, was recognized as one of the primary groups of the animal kingdom. It has now been broken up into several groups, some of which are considered phyla. Included among these are Platyhelminthes, Nemathelminthes, Annelida, and the phyla considered in this chapter. 219.
