nulation which occurs there. In the front view a series of large denti- 
form protuberances are visible around the periphery of the cells; more- 
over a series of about five oblong strong protuberances occur in the 
centre of each semicell. 
Lundell's form is mentioned and figured in his work: De Desmidiaceis 
(p. 24, Pl. II, fig. 10). The Greenland form is somewhat smaller, the 
semicells are relatively less compressed; the cells in the vertical view 
are more inflated at the middle, than in the figure of the main species 
given by Lundell. In the Greenland form the granules are arranged 
around the poles of the cells, moreover a zone of granules occurs a little 
below the middle of each semicell.
