 inch deep. The branches are spreading, and seldom coalesce.

6. OCULINA OCTJLATA. 



O. ramosissima, ramis tortuosis, impkxis et valde coalitis, polypis par- 

 vulis. Corallum caliculis sparsis, scepius obsolescentibus, sed prope 

 apicem prominentibus et cylindrids, l-l^'" latis, lamellis vix exsertis. 



Very ramose, branches tortuous, implicate and much coalescing. 

 Corallum with scattered calicles, mostly obsolescent, but towards 

 the extremities of the branchlets prominent and cylindrical, 1 to \\ 

 lines broad, lamellae slightly exsert, or not at all so. 



West Indies. 



The much-coalesced branches, and the very short calicles of the 

 general surface, and oblong cylindrical calicles of the extremities 

 (sometimes one-fourth of an inch long), are the distinguishing pecu- 

 liarities of this common species. It grows at times to a height of a 

 foot and a half, and branches nearly in a plane. 



This species is the virginea, in part, of Lamarck ; the virginea of 

 the older authors is a Mediterranean species, and appears to be dis- 

 tinct from the above.
