SUPPLEMENT. 695 



T\\e flabelliformis, as the name implies, has its branches in a single 

 plane. It is very ramulous, and the outer branchlets are very deli- 

 cate (plate 60, figure 7). The calicles are a little prominent, or give a 

 zigzag appearance to the branchlets ; the cells are about one-sixth of 

 a line in diameter, and the margin is slightly crenulate, as seen under 

 a lens. As Lamarck states, it somewhat resembles a Millepora.

seven inches by five in breadth, and Gen. xlviii., sp. 2. 

 resembles closely a specimen in the Bos- 

 ton City Museum.
