This fpecies includes three of Gmelin: his ciliatus, ligulatus, and 

 holofetaceus. The frond is at firft membranaceous, divided almoft 

 immediately from the root, the branches -^ or f of an inch broad, 

 the margins fringed with numerous patent cilia. This is Gmelin's 

 ciliatus, t. 21. f. I. but this figure is not nearly fo good as the 

 others. 



In fome fpecimens many ligula are interfperfed among the cilia, 

 which are nothing more than young branches. This is the ligu- 

 latus of Gmelin, f. 3, which certainly is by no means to be confi- 

 <lered as diftinft.
