 Summer. Eatlier rare. Eantry Bay, Miss Ilutcliins ; Larne, 

 Dr. Drummoiid ; Tor Abbey, Mrs. Griffiths ; Belfast Bay,' 

 Mr. Wm. Thompson; Salcombe, Mr. Kalfs; Ardrossan, 

 Major Martin ; Saltcoats, Isabella Landsborough. 



A beautiful species, discovered in Ireland by Miss Hut- 

 chins, whose name is held in grateful remembrance in all 

 parts of the world. See a fine figure of this species in 

 Phyc. Brit., PI. cxxiv. 



7. Cladophora LJiiTEViREXs, Kiltzing. 



Hab. On rocks and on other Alga3 at low-water mark, 

 and near high-water mark. Annual. Summer. Common! 



It is frequent in the early part of the summer, on the 

 coast of Ayrshire. Professor Harvey seems to think that it 

 is the same as C. glomerata, but he yields to Mrs. Griffiths, 

 who is of a different opinion. We have observed that 

 C.fjlomerata retains its colour in the herbarium much better 

 than C. la'tevirens. 



8. CL.IDOPHORA gracilis, Gnffiths. 



Hab. On rocks and Algae. Common on the coast of 

 Ayrshire in early summer, on Alga3 ; colour, a yellowish 

 green, becoming paler in the herbarium, but retaining a 

 silky gloss.
