Abstract I n the ‘History of Rutherglen and East Kilbride’ by the Rev. D. Ure, Parish Minister of East Kilbride, in Clydesdale, there is figured a cup-coral, the description of which refers only to the external form, and the name given to it was simply Fungites . Since then it has received various names from the following writers:— Fungites , Rev. D. Ure, Hist. of Ruth. & East Kilb. p. 327, pl. 20. fig. 6: 1793. Turbinolia fungites , Flem. Brit. Anim. p. 510: 1828. S. Woodward, Syn. Tab. of Brit. Org. Rem. p. 7: 1830. Cyathophyllum fungites , Geinitz, Grund. der Verst. p. 571: 1845–6. Clisiophyllum prolapsum , M'Coy, Ann. & Mag. Nat. Hist. 2nd ser. vol. iii. p. 3: 1849. Aulophyllum prolapsum , Edw. & Haime, Brit. Foss. Corals, Introduction, p. 70: 1850. Aulophyllum fungites , Edw. & Haime, Pol. Eoss. des Terr. Paléoz. p. 413: 1851. Clisiophyllum prolapsum , M'Coy, Brit. Palæoz. Foss. p. 95, Pl. 3C, fig. 5: 1851. Recent investigations into the internal structure warrant us in dissociating it from any of the generic names it has received, and raising it to the rank of an independent genus with a descriptive title. The author then gave descriptions of the genera Cyathophyllum, Clisiophyllum , and Aulophyllum , and of the new genus, Cyclophyllum (Duncan and Thomson). The characteristics of each of these genera are sufficiently marked to warrant their generic distinction. The ascending convex vesicular dissepiments in the middle area, the mesial columella in the vertical section, and consequently the exserted conical boss in the centre of the calice separate the genus Clisiophyllum from the other genera of Cyathophyllidæ. It differs from Cyathophyllum in the latter having no columella, the columellar space being filled up by closely set tabulæ. In Aulophyllum the tube-like mass in the centre of the corallum is occupied by minute tabulæ.
