0. herpobdellae S. and K. (Fig. 254, c). In the testis of Herpobdella 

 atomaria; mature macrogametes 180^ by 30//; microgametes 50m 

 by 12/x; schizogony in April and May; sporogony in June and July. 



Genus Klossiella Smith and Johnson. Microgametocyte produces 

 2 microgametes; oocyst with many spores, each with numerous 

 sporozoites; in the kidney of mammals (Smith and Johnson, 1902). 



K. muris S. and J. (Fig. 254, d, e). Oocyst with 12-14 spherical 

 spores; about 30-34 sporozoites in a spore, 16/x by 13/j; spores dis- 

 charged in the host's urine; in the epithelium of the tubules and 

 glomeruli in the kidney of the mouse, Mus musculus. 



K. cobayae Seidelin. Oocyst with 8-20 spores; spore with about 

 30 sporozoites; in the kidney of guinea pig. 



Genus Legerella Mesnil. Oocyst contains numerous sporozoites; 

 spores entirely lacking; in arthropods (Mesnil, 1900). 



L. hydropori Vincent (Fig. 254,/). In the epithelium of Malpighian
