NiTOPHYLLUM VIOLACEUM, AG. 



This species is distinguished by its very narrow 

 frond, which fofks ahiiost from the bottom, into long, 

 slender segments, and by its marked purple or violet 

 color. It is quite a variable plant, yet one or the 

 other of these marks will usually determine it. It 

 grows to the height of six or eight inches, and its 

 lobes are often not over a quarter of an inch wide, 

 and are apt to throw out at irregular intervals along 

 the margin, minute leaflets with a dark spot in them ; 

 this is the fruit. It is plentiful along the entire coast, 

 and grows in deep water on the larger Algae. 



Genus.— CALLIBLEPHARIS,'' Kutz. 



Calliblepharis ciliata, Kutz. 



The ciliated species of this genus is by no 

 means as common in our waters, as it is reported 

 to be on the other side of the Atlantic, but it will 

 well repay looking for where it may be expected. 

 It is an annual, growing in deep water, and ripen- 

 ing its fruit and frond in early winter. It is found 

 at Cape Ann, and down the coast of New Eng-
