range unknown. Convex or posteal side above the basal plates composed 

 somewhat irregularly of six ranges of plates, having 3 + 4(.5?) +5 + 4 + 4 

 plates respectively, above which the structure is unknown. Lateral or 

 radial plates three known on each side in direct succession, the lower one 

 elongated and very unequally five-sided; the lower angular extremity 

 resting one side against the long basal plate of tlie concave side, and the 

 opposite shorter side resting upon the sloping edge of the adjoining basal 

 plate of the convex side. The second radial plates rest, one side against 

 the lateral margins of the large central plate of the concave side, and the 

 opposite sides adjoin the plates of the convex side ; thus, with the base and 

 summit, giving one of those plates an irregular hexagonal and the other a 

 heptagonal form. Third radial or angular plates heptagonal. Fourth 

 radials unknown. Column unknown." Hall, 1859.
