STENOPHORA. 91 



1. Family STENOPHORID^ Leger & Duboscq, 



1904. 



Development intracellular. Trophozoites solitary. Epi- 

 merite absent or of a simple structure. Gametocysts dehisce 

 by simple rupture. Sporocysts ovoidal, with broad epispore 

 and with equatorial line. Not extruded in chains. Parasitic 

 in Diplopods.

 Gametocysts open by simple rupture. Sporocysts oval, with 

 a broad epispore and with an equatorial line. Not extruded

f Stenophora ellipsoidi, Chakravarti, 1934, pp. 164-8, figs. 1-6. 



Young trophozoite intracellular, with a round epimerite and 

 a bottle-shaped protomerite ; not known to penetrate beyond 

 the nucleus of the epithehal cells. Sporonts ellipsoidal. 

 Epimerite persists for some time. Protomerite in the adult 

 has its posterior end drawn out into a small blunt process 

 which produces a depression in the septum. Deutomerite 

 ellipsoidal, grows more rapidly than the protomerite. Nucleus 

 elhptical and variable in position. Gametocysts spherical, 

 develop outside the body of the host, and dehisce by simple 

 rupture. Sporocysts spindle-shaped, octozoic.
