280 PROTOZOOLOGY 



retained, takes place at each ecdysis of host; in Cryptocercus 

 punctulatus. 



M. xijlopletha C. (Fig. 129, g). 112-154m by 72-127ax. 



Genus Leptospironympha Cleveland. Cylindrical; small; flagella 

 on 2 bands winding spirally along body axis; axostyle single, hya- 

 line; nucleus does not migrate posteriorly during division; en- 

 cystment unknown; in Cryptocercus punctulatus. 



L. eupora C. (Fig. 129, h). 30-38^ by 18-21m. 



Family 2 Lophomonadidae Kent 



Numerous flagella arise from anterior end in a tuft; each 

 flagellum originates in a blepharoplast from which extends in- 

 ward an axostylar filament; nucleus anterior, surrounded by a 

 funnel-shaped space formed by filaments; no cytostome; para- 

 basal body; nutrition holozoic or parasitic; reproduction by bi- 

 nary or multiple fission; encystment common; sexual reproduc- 

 tion unknown; in cockroaches and termite guts. 



Genus Lophomonas Stein. Ovoid or elongate; small; a vesicular 

 nucleus anterior; cysts common; in colon of cockroaches. 



L. hlattarum S. (Figs. 23; 59; 66; 130, a-e). Small, pyriform, but 

 plastic; bundle of axostylar filaments may project beyond pos- 

 terior margin; active swimming movements; binary or multiple 

 fission; 25-30^ long; holozoic in colon of cockroaches; widely 

 distributed. 



L. striata Biitschli (Fig. 130, f-h). Elongate spindle; surface 

 with obliquely arranged needle-like structures which some in- 

 vestigators believe to be a protophytan (to which Grasse gave 

 the name, Fusiformis lopho7nonadis) ; bundle of axial filaments 

 short, never protruding; movement sluggish; cyst spherical with 

 needle-like structures; in same habitat as the last species. 



Genus Eulophomonas Grassi et Foa. Similar to Lophomonas, but 

 flagella vary from 5-15 or a little more in number; in termite gut. 



E. kalotermitis Grassi. In Kalotermes flavicollis; this flagellate 

 has not been observed by other workers. 



Genus Prolophomonas Cleveland. Similar to Eulophomonas; 

 established since Eulophomonas had not been seen by recent 

 workers; would become synonym "if Eulophomonas can be 

 found in K. flavicollis" (Cleveland). 



P. tocopola C. (Fig. 130, i). 14-19m by 12-15^; in Cnjptocercus 

 punctulatus.
