THE EUGLENOIDINA OF OHIO 367 



*17. E. proxima Dang. (Fig. 4, PI. XIII). 



Fusiform, not elongately cjdindrical with colorless tip, meta- 

 bolic; periplast spirally striate; flagellum 1-1 i/o times length of 

 body; nucleus central; chloroleucites numerous, disciform, about 

 50 in each individual ; pyrenoids absent ; paramylon small, elon- 

 gately oval or annular (?). 



Reproduction by encystment with cysts spherical, two cells 

 being formed in a common envelope. 



L. 60-70/^. D. 20/x. 



Distribution, France, Potiers. Storage Dam, Columbus. 



The elongately oval chloroleucites suggests a form somewhat 

 intermediate between those possessing elongated rods and those 

 with flattened disks. 



18. E. caudata Hubner (Fig. 5, PI. XIII). 



Broadly fusiform with narrowed elongate tip, metabolic; 

 periplast spirally striate; flagellum as long as body; nucleus cen- 

 tral ; chloroleucites numerous, dumb-bell shaped ; pyrenoids with 

 a double shell ; paramylon ( ?) . 



Reproduction ( ?). 



L. 110^. D. SSfx. 



Distribution, Europe (?). 



19. E. flava Dang. (Fig. 6, PI. XIII). 



Fusiform with short tip, red, metabolic; periplast (?) ; flagel- 

 lum about length of body; nucleus (?) ; chloroleucites 3-15 in num- 

 ber, disciform; pyrenoids with double shell; paramylon ( ?). 



Development by longitudinal division. Encystment with 

 spherical cysts. 



L. 60//. D. 25-30/7.. 



Distribution, France at Potiers. 



20. E. orientalis Kashyop (Fig. 7, PI. XIII). 



Fusiform approaching cylindrical, color red; periplast (?) ; 

 flagellum about as long as body ; chloroleucites globular ; pyre- 

 noids (?) ; paramylon disiform, about l/x in diameter. 



Reproduction by flask shaped cysts from which it escapes 

 laterally. 



L. 60-120/'. D. 25 (?) -40 (?)/..
