 Belated to the Volvocineae there is a form of alga 

 represented in six positions by fig. 8, on PL XVII. It 

 was met with in two gatherings from two places. It is 

 free from other Coenobial forms, made up of four cells 

 held together by the faintest trace of a matrix ; each cell 

 has dark green contents, clear anterior end, pigment spot, 

 nucleus and a pair of long cilia. When they swim the 

 four cells are drawn after the cilia ; they can spin round 

 rapidly when the cilia may be seen either above or below 

 the cells. 



. Another uncommon form of unicellular character is 

 represented by fig. 9. The cell-wall is distinct with the 

 cell contents which is of a pale green colour, drawn away 

 from the wall except at five points ; a nucleus is clearly 

 seen, but no pigment spot and no hyaline end, a pair of 

 long cilia exerted at one point of attachment. Although 

 there was a steady movement of the organisms throughout 

 the observation, the seven figures represent the appearance 

 during twenty minutes, it was not until the end of this
