THE EUGLENOIDINA OF OHIO 413 



L. 7.5-20/x. D. 7-8/x. 



Distribution, Europe. Intestine of frogs and toads. 



Lemmermann notes Copromonas subtilis Dobell as a synonym 

 of this, while he suggests that Sytomonas pusilla Klebs may repre- 

 sent a distinct genus, the cell being oval, truncate anteriorly, 

 nucleus central, flagellum scarcely as long as body, cytopharynx 

 absent. In cultures of decaying algae, 



2. S. dobelli n.sp. (Fig. 15, PI. XXIII). 



Oval, distinctly narrowed anteriorly; flagellum IV2 times 

 length of body ; nucleus anterior. 



L. 7-10/x. D. S-4iJ.. 



Distribution, Europe. Intestine of Molge vulgaris L., one of 

 the Salamanders. 



It seems evident that this form referred by Lemmermann 

 doubtfully to 5. 7najor should be considered as a distinct species 

 by reason of difference in host, general size, position of nucleus, 

 etc. Therefore it is fitting that it bear the name of the investi- 

 gator by whom it was discovered. 



3. S. major (Berhner), (Fig. 1, PI. XXIV). 



Elongately oval, broadly rounded at the ends; flagellum II/4, 

 times the length of the body; nucleus central. 



L. 20/x. D. op.. 



Distribution. Europe. Digestive tract of Lacerta viridis Gessn., 

 the small green lizard. 



4. Gen. PERANEMA Stein. 



Form spindle shaped, narrowed anteriorly ; strongly meta- 

 bolic ; flagellum longer than body ; pharynx prominent ; rod-like 

 organ present ; pellicula striate spirally ; nucleus central ; para- 

 mylon present; movement a slow swimming one accompanied by 

 decided metabolic contractions of the body.
