This species is very like Melitoea ocliracea, but the cells arc much 

 more numerous and crowded, and the axis is solid and calcareous. 



Esper's figures somewhat represent this species ; but the cells are 

 not sufficiently crowded and numerous in figs. 4 & 5. 



The lateral groove is distinctly marked on the outer side, and 

 more or less indistinctly so on the uppersides of the branches and 

 branchlets.

75. Melitella linearis. B.M. 



Coral very much branched, on a piano ; branchlets very slender, 

 filiform, of a uniform size, coalescing at each joint, leaving oblong, 

 elongate interspaces ; articulations large, swollen, red. Axis white. 

 Cells rather prominent, very few, rather far apart, one or two series 

 on each side of the stem ?
