Diagnosis.— Conical shell wall, not elongated along host axis, not only covered by the 
coenenchyme tissues containing the gorgonian polyps, but entirely embedded in the proteinaceous 
axis of the gorgonian, forming a gall around the shell wall such that only the opercular opening is 
not encased by extensions of the proteinaceous axis material; basis nearly flat with radial grooves 
aligning with plate sutures; summit of plates uneven, summit sloping from high end at top of Cari¬ 
na down to low end at top of rostmm; radii disparietal and wide; parietes covered in short calcare¬ 
ous spines.
