THE EUGLENOIDINA OF OHIO 383 



paramylon consisting of 2 large or several small lateral discoid 

 granules. 



Reproduction, longitudinal division without encystment. 



L. 30-55/x. D. 13-15/.. 



Distribution, cosmopolitan. Standing water. 



15. P. nordstedtii Lemm. (Fig. 10, PI. XVII). 

 Transversely oval with posterior spike distinct, straight, and 



as long as body ; periplast forming wing-like lateral extensions with 

 distinct spiral striae; flagellum as long as body; paramylon (?) . 



Reproduction (?). 



L. 53/.. D. 2V 



Distribution, Europe and Asia Minor. 



16. P. setosa France (Fig. 11, PI. XVII). 



Broadly oval, approaching cylindrical, emarginate anteriorly, 

 the posterior spike pronounced, straight, and as long as body; 

 periplast spirally striate; flagellum (?) ; paramylon in the form of 

 numerous spherical or cylindrical granules. 



Reproduction (?). 



L. 30-31/i. D. 15/x(?). 



Distribution, Europe, Hungary (Balaton). 



Lemmermann notes the length of this species as 30-31/x, which 

 if including the posterior spike would be an extremely small form. 

 The magnification of the figured specimen is given as 610, and if 

 correct makes the actual size approximately 100/. for the total 

 length, which is evidently an error. 



17. P. striata France (Fig. 12, PI. XVII). 



Oval, often broadest posteriorly with posterior spike distinct 

 and 1/2-1/3 the length of the body; periplast spirally striate; 

 flagellum scarcely as long as body; paramylon 1 large discoid 

 granule. 



Reproduction (?). 



L. 20-24/x. D. 4-9/.. 



Distribution, Europe, Hungary (Balaton). 



*18. P. oscillans Klebs (Fig. 13, PI. XVII). 

 Oval, broadest anteriorly, gradually narrowed posteriorly with 

 short but distinct tooth, lateral margins turned in toward the con-
