19. Classification. 
Spengel (231) concludes that the Enteropneusta have no special 
affinities with the Chordata, the Nemertines, or Echinoderms, nor with 
the Annelids, except that the ancestors of both groups have to be sought 
in the Platyhelminthes. He accepts as the nearest allies of the Entero- 
pneusta, Cephalodiscus , Phoronis , &c., but does not discuss the relation- 
ship of these to other animals.
