Gorg. citrina, Esper, ii. 129, tab. 38, 

 " G. ramosa, subplana, ramis compressis 

 brevibus, cortice flavescenle, poris mar- 

 ginalibus vix prominulis." The figure 

 and description agree with specimens 

 seen by the author. The cortex is 

 usually bright sulphur-yellow with a 

 single row of purple dots along the 

 margin of the flat pinnules, about twenty- 

 four of them to an inch in length. The 

 surface is smooth without a sulcus.

 specimens.

 high and ten broad), sparingly ramose; branches erect, simple, much 

 compressed and flat, throughout four and a half inches long, and one
