G7G PROTOZOOLOGY 



sporoplasm uninucleate; extruded polar filament 80-95/x long (Perez, 

 1908; Kudo, 1942). 



Genus Trichoduboscqia Leger. Similar to Duboscqia in number of 

 spores produced in each sporont; but sporont with 4 (or 3) rigid 

 transparent prolongations, difficult to see in life. One species. 



T. epeori L. (Fig. 291, p, q). In fat-bodies of nymphs of the may- 

 flies, Epeorus torrentium and Rhithrogena semicolorata; sporonts 

 spherical, 9-10/* in diameter, with usually 16 spores; prolongations of 

 membrane in sporont, 20-22/* long; spores pyriform, 3.5-4/* long 

 (Leger, 1926). 



Genus Plistophora Gurley. Sporont develops into variable number 

 (often more than 16) of sporoblasts, each of which becomes a spore. 

 Several species. 



P. longifilis Schuberg (Figs. 287, e; 291, r, s). In the testis of 

 Barbus fluviatilis; spores 3/x by 2/i to 12/i by 6/*; extruded polar fila- 

 ment up to 510^ long. 



P. kudoi Sprague and Ramsey. In the epithelial cells of the mid- 

 gut of Blatta orientalis; fresh spores about 3.2/* by 1.75/*; polar fila- 

 ment 25-50/* long. 



Genus Pyrotheca Hesse. Schizogony and sporogony unknown; 

 spores elongate pyriform, anterior end attenuated, posterior end 

 rounded, slightly curved; sporoplasm in posterior region, with 1-2 

 nuclei; polar capsule large. One species (Hesse, 1935). 



P. incurvata H. (Fig. 292, a, b). In fat-bodies and haemocoele of 

 Megacylcops viridis; spores 14/* by 3/*; polar filament 130/* long. 



Family 2 Coccosporidae Kudo 



Genus Coccospora Kudo (Cocconema Leger and Hesse). Spore 

 spherical or subspherical. Several species (Leger and Hesse, 1921, 

 1922; Kudo, 1925b). 



C. slavinae (L. and H.) (Fig. 292, c, d). In gut-epithelium of Slavina 

 appendiculata; spores about 3/* in diameter. 



Family 3 Mrazekiidae Leger and Hesse 



Genus Mrazekia L. and H. (Myxocystis Mrazek). Spore, tubular 

 and straight; a long or short process at one extremity (Leger and 

 Hess, 1916). Species (Jfrovec, 1936a). 



M. caudata L. and H. (Fig. 292, e, /). In the lymphocytes of 

 Tubifex tubifex; spore cylindrical, 16-18/* by 1.3—1.4/*, with a long- 

 process. 



Genus Bacillidium Janda. Spore cylindrical, but without any proc- 

 ess; one end narrowed in a few species (Janda, 1928). Several species 

 (Jfrovec, 1936a).
