Chlorophycea, and in point of fact a Chetophora. Since it is evidently 
the same alga which Kiitzing figures, it can, therefore, only belong to 
the species Ch. punctiformis—the more 80 that it possesses very 
ristic peculiarities. If the tiny cushions scraped from the

generally possessed of scanty contents or destitute of contents, and 
corresponds to the many-celled hair, in which the branches terminate 
in many other species of Chetophora; the diameter of the cells in the 
middle portion of the thallus amounts to 6-8». The structure 0 
the thallus in this case is, therefore, corresponding to its ace
