The suborder is here divided into the following two famiUes: 



Parasitic in the epithelium of the digestive tract and its appended glands of 

 chiefly invertebrates Family 1 Adeleidae 



Parasitic in the cells of the circulatory system of vertebrates 



Family 2 Haemogregarinidae 



Family 1 Adeleidae Leger 



Genus Adelea Schneider. The zygote develops into a thinly 

 walled oocyst which contains numerous flattened spores, each 

 with two sporozoites. In arthropods. 



Adelea ovata Schneider (Fig. 116). In the centipede, Litho- 

 hius forficatus. 



Genus Adelina Hesse. The oocyst is thick-walled. The 

 spore is spherical and comparatively small in number.

 tine of various species of myriapods belonging to the genus 

 Scolopendra. 



Adelina octospora Hesse (Fig. 117, h). The spherical oocyst 

 contains eight spores. In the coelom of Slavina appendiculata.
