244 SEA MOSSES. 



three or four times longer than broad. Toward the 

 apices these shorten, till they are not much longer 

 than the colored bands. The apices are sometimes 

 only incurved, but more frequently hooked. 



It may always be distinguislied from the next, 

 with which only is it likely to be confounded, by 

 its somewhat greater length; its narrower forking; 

 its decided tinge of purple in the prevailing 

 red, of the dry plant; and the fact that the 

 fronds of a tuft appear to be of, a considerably 

 different length, so that the outline of the mounted tuft 

 will be decidedly uneven and jagged. I collected it 

 in abundance at Newport and Wood's Holl, in the 

 summer and fall. I have never found it in Massachu- 

 setts Bay. But Mr. Collins reports it as not uncommon 

 in the warm waters, on the muddy bottom of Mystic 

 river marshes, about Boston. And Mrs. Davis collects 

 it in the river, at Little Good Harbor, Gloucester. 



Ceramium fastigiatum,* Harv. 



This I consider our most beautiful Cramium. It 

 is very common at all points, where I have visited 

 the south shore of New England and New York, 

 especially at Newport, where I took hundreds of 

 splendid plants. It grows on Zostera, Chondrus 



* Fastigiatum = Sharp pointed.
