Ivi BRITISH FOSSIL CORALS. 4. Gentis Microsolena. Lamouroux, Exp. meth., p. 65, 1821. Corallum differing from the preceding genus by the structure of the septa, the perforations of which are much larger than in Coscinaraja, and 1)y the existence of a strong, common epitheca. Typ. sp., Mierosoleua fiorosa, Lamouroux, op. eit., tab. Ixxiv, fig. 24. 5. Genus Goniopora. Quoy and Gaimard, Voy. de I'Astr., Zooph., p. 218, 1833 ; Goniopora and Porastrea, Milne Edw. and J. Haime, Comptes rend, de I'Acad. des Sc, t. xxvii, p. 49fi, 1848. Corallum having distinct, elevated vtâlls, of a fenestrate structm-e. Callces deep. Columella spongy. Septa well developed, and fenestrate. No pali. Typ. sp., Goniopora pedunculata, Quoy and Gaimard, Voyage de I'Astrolabe, Zooph., tab. xvi, figs. 9-11. 6. Genus Rhodarâ. Milne Edw. and J. Haime, Comptes rend., t. xxis, p. 259, 1849. Corallum with thick walls, rather high. Septa rudimentary. Pali greatly developed, and forming a rosette in the centre of the calice. p. 266. Typ. sp., Rhodarcea calicidaris, nob.; Astrea ealicidaris, Lamarck, Hist, des An. sans Vert., t. ii, 7. Ge7ius Porarâ. Milne Edw. and J. Haime, Comptes rend., t. sxix, p. 259, 1849. Walls thin, and widely fenestrated. Septa formed by a series of spiniform processes, which sometimes ramify towards the centre of the visceral cavity, so as to constitute a sort of spurious columella. Typ. sp., Poraraa fenesfrata, nob. ; Poeillopora fenestrata, Lamarck, Hist, des An. sans Vert., t. ii, p. 275 ; Milne Edw. and J. Haime, Ann. des Sc. Nat., Z"" serie, vol. ix, fig. 1. 8. Ge?ms Holar^â. Milne Edw. and J. Haime, Comptes rend., t. xxix, p. 259, 1849. Calices mth distinct polygonal margins, rather deep. Septal apparatus composed of irregular trabiculse, completely blended with the walls, and constituting thus a delicate spongy mass. Columella fasciculate and short. Typ. sp., Holaraa Parisiensis, nob. ; Alveolites Parisiensis, Michelin, Icon. Zooph., pi. xlv, fig, 10.
. INTRODUCTION. Ivii Second Tribe—MONTIPORIN.E. CcBnenchyma abundant and spongy. 9. Genus Alveopora. Quoy and Gaimard, Voyage de 1' Astrolabe, Zooph., p. 240, 1833. Corallum arborescent. Cmnenchi/ma very porous and ecliinulate, but not bearing large excrescences. Margins of the calices scarcely distinct. Septa not numerous, and formed by series of spiniform processes. No columella. Typ. sp., Alveopora rubra, Quoy and Gaim., loc. cit., Zoopb., tab. sis, figs. 11-14. 10. Genus Montipora. Quoy and Gaimard, op. cit., p. 247, 1833; Manopora, Dana, Zooph., p. 489, 1846. Corallum of various forms, differing from Alveopora by the existence of large projections of the coenenchyma between the cahcules. Ccenenchpiia much more abundant, and more delicately spongy. Typ. sp., Montipora verrucosa, Quoy and Gaim., op. cit., Zoopb., pi. x.\, fig. 1 1 11. Ge7lUS PsAMMOCORA. Dana, Zoopb., p. 344, 1846. CfBnencliyma somewhat compact, of a fasciculate structiu-e, and having its surface papillose. Calices very shallow, confluent, and without distinct walls. Septa thick, and formed by strong spiniform processes. Typ. sp., Psammocora obtusata, Dana, loc. cit., p. 345 ; Pavonia obtusangula, Lamarck, Hist, des An. sans Vert., t. ii, p. 240. Sub-order 3. ZOANTHARIA TABULATA. Corallum essentially composed of a well-developed mural system, and having the visceral chambers divided into a series of stories by complete transverse tabulae or diaphragms. Septal apparatus rudimentary. The principal character of this sub-order is founded on the existence of the lamellar diaphragms that close the visceral chamber of the corallites at different heights, and chffer from the dissepiments of the Astreida; by not being dependent on the septa, and forming as many complete horizontal divisions extending from side to side of the general cavity, S
