and anaemic, and, as the name of the species implies, 
a disintegrating action on the nucleus is one of its 
effects. The nucleus is either pressed to the side or 
broken up into fragments. 
The parasite in its endoglobular stage becomes 
surrounded with a cytocyst . Some of these cysts divide 
up into about a dozen macromerozoits (Fig. 88), while 
others divide up into twice as many or more micro- 
merozoits. Corresponding to these we have free forms 
in the liver, twelve by three ^ and eight by two pc 
respectively. It is said to be transmitted by ticks in 
the larval and nymphal stage.

the blood of lizards. The vermicules have a peculiar 
shape (Fig. 88). Here also cyst formation has been 
described in the spleen by Labbe.

Has a destructive action on the nuclei of the red cells. 
They flatten and elongate, and also fragment. Para¬ 
site is reniform, 15-18^ by 5-6//. The protoplasm has 
numerous granules.
