motile cells, also biciliate, are formed, which escape by solution of 

 the cell-wall. They swim towards the light, and conjugate in 

 pairs. The germination of the zygospore is unknown, and it is 

 not absolutely proved that the sexual and asexual forms belong to 

 the same plant. It seems very likely, as Dr. Reinke suggests, that 

 this curious plant is really co-generic with the Chcetopeltis 

 described by Mobius in the Berichte d. deutschen bot. Gesellschaft, 

 1888, p. 242. 



We shall look forward with great interest to the continuation 

 of this beautiful work, which does equal credit to the author, the 

 artists, and the enlightened government department which is 

 presiding over its publication. D. H. Scott.
