RED ALGyS. 1G3 



teristic ramuli, one-fourth to one-haU an inch long, 



slender and attenuated to a sharp point, both at 



the top and at the place of insertion on the branch. 



In drying, the plant adheres well to paper. It 



grows between tides, on Fucus and on rocks. It is 



a summer annual, inhabiting Long Island Sound and 



adjacent waters. I have collected it only at Wood's 



Holl. Miss Booth reports it in great abundance in 



Peconic Bay. 



Chondriopsis striolata, Ag.

 into many long, simple, or once or twice compound 

 branches. The branches rise somewhat perpendic- 

 ularly, and make a compact tuft of the plant. The 

 ramuli are very plentiful, much constricted at the 

 base, somewhat rounded at the apex ; standing near 

 the next species, in this respect, as it does near 

 the last in its slender habit. The ramuli not unfre- 

 quently bear like secondary ramuli along their sides. 

 This is the characteristic point in the plant, though 

 it sometimes occurs in C. dasyphylla. This species 

 grows on rocks and other Algas, in pools, between 

 tides, and below. I have taken it, at low-tide, in 

 great abundance, on the rocks, east of the first 

 beach, at Newport, in July and August. It is plen-
