374 OHIO BIOLOGICAL SURVEY 



Distribution, Mt. Vernon (Hiawatha Lake), O. 



This species has been found in almost all cultures from Hia- 

 watha Lake, at Hiawatha Park, Mt. Vernon, during a period of 

 three years. Large paramylon granules are absent, while the 

 emarginate posterior end of the body is a character of interest. 

 The body is often twisted into bipartate or tripartate areas similar 

 to E. tripteris. 



The species is allied to E. ehrenbergii Klebs to which Ambhj- 

 ophis viridis Ehrenb. (Kent, V. 1, p. 386) must be referred but 

 differs by the characters in the "Table." Amblyophis aegyptiaca 

 Schmarda (fresh water Egypt) is not sufficiently described to place 

 it with certainty, systematically. 



38. E. quartana Moroff (Fig. 5, PI. XV). 



Colorless, fusiform, gradually narrowed behind, decidedly 

 metabolic ; periplast distinctly differentiated, thick but smooth ; 

 flagellum II/2 times length of body; nucleus in posterior third of 

 body; chloroleucites absent; paramylon granules usually oval, com- 

 paratively large. 



Reproduction (?). 



L. 50ju. D. 15/x. 



Distribution, Germany (Munich). 



The species was described by Moroff in cultures made from 

 drainage water at Munich in which Beggiota had developed in 

 quantities. It should be regarded as a valid species with some 

 doubt by reason of the possible loss of the chlorophyl due to arti- 

 ficial conditions. 



2. Gen. LEPTOCINCLIS Party. 



Forms radial not compressed usually with periplast striate 

 spirally, not metabolic. Flagellum and vacuole system as in 

 Euglena. Chloroleucites numerous, disciform in form and nor- 

 mally contiguous to the pellicula. Usually provided with two large 

 lateral annulate paramylon granules. Reproduction through di- 

 vision in a resting stage. Nourishment holophytic or saprophytic. 



Distribution, cosmopolitan.
