Palaeozoic Corah from Northern Queensland. 279 the tubes are extensively porous and cribriform, being pierced by numerous apertures, which place the visceral chambers in direct communication. Transverse sections also serve admir- ably to show the character of the irregular trabecular septa, some of which are simply spiniform, while others divide towards their inner extremities, or even unite with their neighbours by their free ends. Vertical sections show that the septa are, upon the whole, placed in longitudinal rows; and they exhibit occasionally horizontal trabecules (fig. 3, B), which may be regarded as of the nature of rudimentary tabular Fia:. Part of a transverse section of Areeopora australis, Nich. & Eth., Jun., enlarged eight times, showing the trabecular septa and porous walls. B. Part of a vertical section of the same, similarly enlarged, showing the cribriform character of the walls, the septa, and the rudimentary tabulse. Devonian, Queensland (Daintree collection). From a consideration of the above characters it cannot be doubted that we have to deal in Areeopora with a genuine " Perforate " Coral, which, however, is closely related to the Favositidas, and may be best placed in this family rather than in any of the more regular groups of the Perforata. By the characters of its walls and septa the genus presents certain alliances with the Poritidae ; but its general form and aspect are those of a Favosites; and the presence of rudimentary tabulse would further confirm the view here taken. Among the genera of the Favositidre its nearest ally is to be found in.
