428 PROTOZOOLOGY 



sporozoite; endospore with many small spinous projections. 

 E. lahhei L. (Fig. 193, n). In gut of Lithohius mutabilis; oocyst 

 spherical, 30-40/i in diameter; spores, ll/x by 9.4/x, with bi-valve 

 shell; sporulation completed in about 20 days. 



Suborder 2 Adeleidea Leger 



The Adeleidea are on the whole similar to Eimeridea in their 

 habitat and development, but the micro- and macro-gametocytes 

 become attached to each other in pairs during the course of de- 

 velopment into gametes (Fig. 194), and each microgametocyte 

 produces a few microgametes. The zygote becomes oocyst which 

 produces numerous sporoblasts, each of which develops into a 

 spore with 2 or 4 sporozoites. 



In epithelium of gut and its appended glands of chiefly invertebrates.

Family 1 Adeleidae Leger 



Genus Adelea Schneider. Zygote develops into a thinly walled 

 oocyst with numerous flattened spores, each with 2 sporozoites; 

 in arthropods.

Genus Adelina Hesse. Oocyst thick-walled; spores spherical, 

 comparatively small in number; in gut or coelom of arthropods 

 and oligochaetes.

 in coelom of Slavina appendiciilata. 



Genus Klossia Schneider. Oocyst with numerous spherical 

 spores, each with 3-10 sporozoites. Several species. 



K. helicina S. In kidneys of various land-snails, belonging to 

 genera Helix, Succinea, and Vitrina; oocyst with a double en- 

 velope 120-180/1 in diameter; spores 12^ in diameter, with 5-6 

 sporozoites.
