22. Distribution of Parasitic Forms according to their Hosts. 
a. General. 
Parona (189) discusses parasitism in relation to hosts in general, and 
introduces the new terms “ homopolyhelminthesis,” for where there are 
many worms all of one species in one host, and “ allopolyhelminthesis,” 
where there are several different species.
