198 THE SPOROZOA 



Epim. large, lancet-shaped. Sporonts solitary, the body elongated and 

 cylindrical in form, with globular protom. Cysts without sporoducts. 

 Spores ellipsoidal with thick sporocysts. Unique species C. lutea, A. Schn., 

 from digestive tract of Glomeris sp. Genus 30. Stenophora, Labbe", 1899 

 (nom. nov. for Stenocephalus, A. Schneider, 1875, preoccupied). Sporout oval, 

 obese, with small conical protomerite. Cysts without sporoducts. Spores 

 fusiform with a dark equatorial line. Unique species & juli (Frantz.), 

 from the digestive tract of millepedes, Julus sabulosus and terrestris, 

 Spirobolus marginatus. 



FAMILY 4. DIDYMOPHYIDAE, Le"ger. Sporonts always associated in 

 pairs, one behind the other, in such a way that the protomerite of the 

 satellite disappears, and each syzygy resembles an individual with three 

 chambers and two nuclei (Fig. 25, a). 



Genus 31. Didymophyes, Stein, 1848. Epim. in form of a cylindro- 

 conical spike (Fig. 25, 6). Cysts dehiscing by simple rupture. Spores oval. 

 D. paradoxa, St., from the intestine of Geotrupes stercorarius ; and three 

 other species. 



FAMILY 5. DACTYLOPHORIDAE, Leger. Epimerite asymmetrical, 

 irregular, bearing digitiform or root-like prolongations (Fig. 1 7, h, i). The 

 dehiscence of the cysts is effected by simple rupture or by means of a 

 pseudocyst (p. 183) placed laterally. Spores elongated, cylindrical (Fig. 34, 6). 



Genus 32. Rhopalonia, Leger, 1893. Epim. a subspherical knob 

 bearing flexible digitiform processes. Trophozoites solitary, the conical 

 body not septate, but with an indication of the protomerite. Unique 

 species R. geophili, Leg., from digestive tract of Geophilidae and of- 

 Stigmatogaster gracilis. Genus 33. Echinomera, Labbe, 1899 (nom. nov. 

 for Echinocephahis, A. Schneider, 1875). Trophozoite of oval or subconical 

 contour, massive ; epim. persistent, spiked, the point furnished with small 

 digitiform appendages which are not persistent, the whole forming with 

 the protomerite a cone with summit displaced and slightly excentric 

 (Fig. 1 7, h). Cyst dehiscing by simple rupture. Spores cylindrical with 

 rounded bases, usually in strings (Fig. 34, b). Unique species E. hispida 

 (A. Schn.), from the gut of Lithobius forficatus. Genus 34. Trichorhynchus, 

 A. Schneider, 1882. Cephalont with cylindrical or truncated protom., 

 bearing an elongated conical rostrum. Cysts oblong with wart-like emi- 

 nences ; dehiscence by means of a lateral pseudocyst. Spores cylindrical 

 or ellipsoidal, not in strings. Unique species T. pulcher, A. Schn., from 

 the digestive tract of Scutigera. Genus 35. Pterocephalus, A. Schneider, 

 1887. Trophozoite with bilaterally symmetrical protom., divided into 

 two lobes bearing spines or root-like processes, the two lobes united at 

 one of their extremities to form a coiled horn (Fig. 17, i). Spores oval 

 in form, connected obliquely into strings. Unique species P. nobilis, 

 A. Schn., from the gut of Scolopendra spp. Genus 36. Dactylophorus, 

 Balbiani, 1889. Protom. expanded excentrically, and carrying the 

 digitiform processes of the epim. Sporonts solitary, of elongated form. 

 Cysts dehiscing by means of a lateral pseudocyst. Spores cylindrical. 

 Unique species D. robwtus, Leg., from the gut of Cryptops hortensis. 



FAMILY 6. ACTINOCEPHALIDAE, Leger. Sporonts always solitary ; 

 epim. symmetrical, simple or with appendages. Cysts dehiscing by
