Ibid., op. cit., pi. iii, f. 2. 1873.--Lindstrom (G ).1--This author, in describing Swedish Lower Silurian corals, mentions an example of H. escharoides, Lamk., from Dalarne, in which the spiniform septa unite at the calicinal centres to form irregular spongy masses, thus confirming Fischer-Benzon's description of his false columella. 1873.--Lindstrom (G.).2--The same writer, in an article on the "Anthozoa Tabulata," described two forms of zooids in Haly sites as in Heliolites. He remarked that between the larger zooids (autopores), with their widely-spaced tabulae, occurred smaller vesicular tabulate tubes ("coenenchyma," or our mesopores). 1876.--Bominger (C.).8--Dr. Rominger united H. catenularia, Linn., H. escharoides, Lamk., and H. labyrinthica, Goldf. He recognised in a generic sense twelve septa ("longitudinal crests") and "flat diaphragms" (tabulae), but did not make any reference to corallites of more than one order, although in one figure4 at least mesopores are shown. 1879.--Nicholson (H. A.).5--At the time my deceased friend wrote his masterly work on the "Palaeozoic Tabulate Corals," he had not seen Dr. Fischer-Benzon's paper, and he restricted his observations to the two typical Edwardsian species. He distinguished H. catenularia by the presence of zooids of two orders and no septal spines, and H. escharoides by the possession of corallites of one order only, and these with twelve septal spines to a cycle. The great value of Nicholson's observations lay in his confirmation of Lindst...
