dentibus et appressis, apice obsoletis. Corallum cellis breviter stellatis, 

 columella valde conspicud, per lameUam ad latus conjuncta. 



Hemispherical, branches subdivided, rather remote, straight, thin (2 

 to 3 lines), much compressed and complanate, \ to \\ inches wide, 

 verrucae small, ascending, and appressed to the branch, obsolete at 

 apex. Corallum having the cells short stellate, columella very dis- 

 tinct, and united by one of the lamellae to the side of the cell.

Sandwich Islands. 



This species is peculiar in its thin-compressed branches, and small 

 appressed verrucas, rather distant and sometimes running in longitu- 

 dinal carinate lines. The intervals between the branches are from \ 

 to | of an inch wide, and give an open appearance to the clumps. It 

 has the habit of the plicata in its distant verrucse and cell, but the 

 branches are very much narrower.

The clumps are ten or twelve inches in diameter, evenly convex or 

 hemispherical, and consist of nearly simple stems, with neatly verru- 

 cose sides, and naked summits. The branches are half to one-third of 

 an inch apart. They are much thinner and the verrucae are smaller
