In text-fig. 26 a large pyriform parasite is represented with 

 less well-marked masses of chromatin, the larger of which is 

 irregular in shape. 



The loose mass of cliromatin was not always to be found in

These are not very common, and the parasites may occur 

 either singly or in pairs — usually only one in a corpuscle.
