polyps green, and having one of the tentacles much longer than the 

 others. Corallum having the branchlets obtuse, the apical calicle 

 short, y of a line broad ; other calicles crowded, labellate, broad and 

 spreading, with the lip much flattened ; cells stellate, two of the 

 lamellae a little the broadest.

This species, as observed by the author, grows horizontally, from a 

 lateral attachment. It is distinguished by its neatly terete branches 

 and branchlets, and broad equal calicles closely crowded upon one 

 another, and standing nearly erect on the surface of the branchlets. 

 The branches are sometimes proliferous, but never acervate so as to 

 lose their terete forms. Its stellate cells, as well as other characters, 

 remove it from the surculosa.

 inches long and 2 to 3 lines thick, nearly simple. Corallum having 

 the calicles labellate, but quite small and very short or scarcely
