This corallum has the form of a cylindroid, elongated cone, and is not contracted just 
above its basis, nor inflated near the calice (figs. 3, 3 4); sometimes only the cone is 
somewhat shorter in proportion to its length (fig. 3a). The coste are very thin, sharp, 
straight, and very prominent from top to bottom, but particularly so near the basis of the 
corallum. The secondary cost are nearly as long as the primary ones ; they do not, 
however, originate quite at the same level. ‘The tertiary costee begin to appear about half 
way up the wall in young specimens, and occupy two thirds of the height of the Coral in
