Van Beneden and Hesse distinguish four groups of Vermes : 
Annelides, Nematoides, Cotylides, and Teretularides. Coty- 
lides they subdivide into Polypodes (=Peripates), Bdellodes, 
Trematodes, and Cestodes. 
Schneider, after a brief review of the chief modifications of 
the muscular system among the leading groups of Vermes^ 
proposes to arrange these animals as follows ; — 
I. Nematelminthes : 
Nematoidep; Chaetognatha ; Chaetophora. 
II. Rhynchelminthes : 
Acanthocephala ; Gephyrea.
