This alga, by reason of its small families of densely-crowded cells 
and the nature of its integument, differs considerably from any other 
genus of Palvnt llacea .

.After enumerating the characters of his "First Subgenus" of 
Hcemdtococcus Ag., Hassall (Brit. Freshw. Alg. i. 322) says that "the 
term Ouracoccus might be applied to the species of this subgenus." 
Improving on this suggestion, Kiitzing, according to the reference on 
p. 206 of his " Species Algarum," establishes the genus Urococcus of 
Hassall ; but it cannot be held to constitute publication of a new 
genus, and, if Urococcus is to stand, it must be as Urococcus Kiitz.
