Part of a tangential section, taken just below the surface, enlarged eighteen times, showing the large and small corallites and the interspersed spiniform corallites. B. Part of the same section, enlarged fifty times. C. Part of a transverse section of a branch, in the axial region, enlarged eighteen times, showing the thin-walled, polygonal, and unequal-sized corallites of this part of the corallum. D. Part of a longitudinal section in the median plane, showing the corallites in the outer portion of their course, where tbeir walls are thickened. The section shows the larger and smaller corallites, the former with remote, and the latter with close-set, tabulae. From the Cincinnati group, Ohio. that in their central portion we find the axial corallites to be polygonal in shape, and to be bounded by very thin and deli- cate walls (fig. 4, C), which, as before, are wholly imper- forate. There is also now a total absence of the smaller interstitial corallites, these latter being confined to the exterior zone of the branches, and not extending into the deeper parts of the corallum. (c) Longitudinal sections show different characters accor- ding to the precise point at which they are examined. In.
