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 Palmdlacea'.

After enumerating the characters of his " First Subgenus " of 

 Hwrnutococcna Ag., Hassall (Brit. Freshw. Alg. i. 322) says that "the 

 term Ouracoccun might be applied to the species of this subgenus." 

 Improving on this suggestion, Klltzing, according to the reference on 

 p. 20G of his " Species Algarum," establishes the genus Urococcus of 

 Hassall ; but it cannot be held to constitute publication of a new 

 genus, and, if Urococcua is to stand, it must be as Urococcus Kiitz.
