Fig. 7. 42. A. Peristome of Epalxis showing peiistoniial wall and bases 

 of adoral membranellcs; diagrammatic (after Kahl). B. Transverse section 

 of Epalxis bidens through the peristome; diagrammatic (after Kahl). C. 

 Atopodinium fibulatum Kahl, 35-45/i (after K.). D, E. Epalxis striata Kahl, 

 25-35^, right and left sides (after K.). F. Pelod'niiuni reuifonne Lautcrborn, 

 40-50^ (after Kahl). G, H. DiscoiuorpJia pectinata Levander, about 80^ long; 

 ventral and lateral views (after Kahl). I. Mylestoina anat'nium (Penard) 

 Kahl, 20-28;u (after K.). J. Saprodinium integrum Kahl, 40-55;Lt (after K.). 



Family 2. Mylestomidae. The right and left dorsal rows of cilia have 

 disappeared and the ventral cilia are absent or reduced in number (Fig. 

 7. 42, C). The reinaining posterior cilia may remain free or may be fused 

 into one or tAvo long "rudder-cirri" (Fig. 7. 42, I). The frontal band is 

 limited to the ventral surface. The posterior end of the body is almost or 

 completely covered with armor.
