appear to be hollow, but their walls are greatly thicker than 
the rest of the frond. Under the microscope, this species 
has the character of a fine piece of mosaic pavement.

It is difficult to say whether this species should be referred 
to Paimella or to Ulva. It has a firmer and more membra- 
nous substance than most Palmelle, and a thicker frond than 
any Ulva with which we are acquainted. Yet the frond 
seems composed of a single stratum of cellules, and there- 
fore perhaps it might be admitted into Ulva, where it would 
stand near U. furfuracea.
