548 PROTOZOOLOGY 



Family 7 Monoductidae Ray and Chakravatry 



As in the last family solitary; but cyst with a single sporoduct or 

 none; spore with 8 sporozoites. 



Genus Monoductus R. and C. Sporadins solitary; epimerite a 

 small elevation with prongs attached to its base; anisogamy; cyst 

 with a single sporoduct; spores flattened fusiform, with dissimilar 

 ends, each with 8 sporozoites. One species. 



M. lunatus R. and C. (Fig. 233, m-o). Cephalins 225-445/* by 

 33-4 7/x; epimerite with about 16 prongs; nucleus parachute-shaped, 

 with myonemes attached at posterior margin; sporadins develop 

 posterior pseudopodial processes before association; cysts spherical, 

 225-230m in diameter, voided by host; development completed in 

 3-4 days outside the host body, with one duct; spores 10.25m by 4/x, 

 truncate at one end, attenuated at other and discharged in a single 

 chain; in gut of Diplopoda sp. 



Genus Sphaerocystis Leger. Sporadins solitary; without protomer- 

 rite; spherical. 



S. simplex L. Sporadins 100-140/z in diameter; protomerite in 

 young trophozoites; spherical cysts in which individuals are not 

 associative, 100m in diameter; spores ovoid, 10.5m by 7.5m; in gut of 

 Cyphon pallidulus. 



Genus Lepismatophila Adams and Travis. Epimerite a simple 

 knob; cysts without ducts; spores ellipsoidal, smooth, in chain. One 

 species (Adams and Travis, 1935). 



L. thermobiae A. and T. (Fig. 233, g-4). Sporadins 67-390^ by 

 30-174ju; cysts white to black, ellipsoidal to subspherical, 244-378/z 

 by 171-262ju; spores brown, 13.6m by 6.8m; in the ventriculus of the 

 firebrat, Thermobia domestica. 



Genus Colepismatophila Adams and Travis. Similar to the last 

 genus; but larger; spores in wavy chains, hat-shaped, with 2 curved 

 filamentous processes attached at opposite ends. One species. 



C. watsonae A. and T. (Fig. 233, j-l). Sporadins 92-562m by 55- 

 189m; cysts 226-464/i by 158-336m; spores 16.5m by 9.7m, processes 21m 

 long; in ventriculus of Thermobia domestica (Adams and Travis, 1935). 



Genus Hyalosporina Chakravarty. Sporont solitary; epimerite 

 small, tongue-like; anisogametes; cyst without ducts; spores oval, 

 with a hyaline membrane. One species (Chakravarty, 1935, 1936X- 



H. cambolopsisae C. (Fig. 234, g-j). Trophozoites 247-1 11 1m by 

 37-1 11m; cysts oval, 292-390m by 263-375m; spores 8m; by 6m; in the 

 gut of the milliped, Cambolopsis sp.
