 We  are  of  opinion  that  this  and  the  next  species,  as  well  a,s  the  
 Palmella Mooreana  figured  on  the  oth  plate  of  this  work,  are  all  one  
 species.

 It is very  doubtful whether any definite specific character can he found  
 to  separate  ihis  from  A.  prasina.  As  we  have  taken  both  from  the  
 same pond,  the  difference  in  colour,  and m  the size of  the cells,  may  be  
 assumed to be attributable only to difference in  age.
