BUSELLA. 



Coral fan- shaped, forming an oblong frond, very much 

 branched and closely reticulated, with a number of short 

 club-shaped branchlets diverging from the sides of the frond ; 

 branches and branchlets cylindi'ical, diverging, fm-cately 

 branched. Bark thin, granular, smooth. Polype-cells on 

 all sides of the branches and branchlets, sunken, close toge- 

 ther, with a small round mouth. Axis continuous, homy, 

 black. (Plexauridee.) 



Busella occatoria = Iihiindogorgia occatoria^ M.-Edw. & 

 Haime, Corall. i. 179. 



Hah. Guadeloupe. B.M. 



MURITELLA. 



Coral branched in a plane ; stem much compressed, broad ; 

 branches and branchlets subcylindrical, apex subclavate. 

 Bark rather thick, granular, with a uniform smooth surface. 

 Polype-cells large, entirely sunken, scattered over the whole 

 surface of the bark, with a very small. contracted linear mouth. 

 Axis of the stem and lower branches compressed, homy, of 

 branchlets cylindrical, with a horny external coat, and with 

 soft pith within. (Plexauridae.)
