150 BRITISH FOSSIL CORALS. 



Caryophyllia quadrifida, Howse, Trans, of the Tyneside Nat. F. C, vol. i, p. 260, 1848. 

 Petraia profunda, King, Perm. Foss. of England, p. 23, tab. iii, fig. 2, 1850.

" Form conical, and slightly curved. Cavity deep and longitudinally furrowed. Plates 

 of two lengths, the longest five or more in number, plain edged (?), and reaching half way 

 to the centre ; the shortest from one to four in number. Lamellar interspaces with two 

 very finely denticulated, slightly prominent ridges. 



" I have only succeeded in procuring two or three specimens from the shelly mag- 

 nesian limestone at Humbleton Quarry. Geinitz states its having been found in the lower 

 Zechstein at Eisleben, Ilmenau, Gerbstedt, and between Hettstadt and Leimbach." {King, 

 op. cit.) 



Aulopora Voigtiana, King, op. cit., p. 31, pi. iii, fig. 13, appears to be a Bryozoum. 



CHAPTER XIV. 

 CORALS FROM THE MOUNTAIN LIMESTONE. 



The Fauna of the Mountain Limestone Period is one of the richest in true Polypi ; 

 seventy-six species have already been found in the deposits appertaining to this geological 

 division, and the presence of none of these Corals has, as yet, been satisfactorily proved 

 in beds belonging to any other period. Forty-three of these species are British, and 

 they are referable to six families : — Milleporidse, Favositidae, Seriatoporidse, Auloporidae, 

 Cyathaxoniidae, and Cyathophyllidae ; but the Favositidae and the Cyathophyllidac are the 

 forms which have the most numerous representatives among these Fossils. 



The principal localities from which they have been obtained, are Castleton, Bake well, 

 Oswestry, Derbyshire, Bolland in Yorkshire, Masbury, near Mendip, in Somersetshire, 

 the environs of Bristol, Kendal in Westmoreland, Wellington in Shropshire, Mold, 

 Lilleshall, Frome, Clifton, &c, in England ; the Isle of Man ; Armagh, Enniskillen, 

 Kulkeag (Fermanagh), Wexford, and Easky (Sligo), in Ireland. 



Most of the Carboniferous Fossils that we have represented in the plates joined to this 

 Monograph, belong to the Collections of the Geological Society of London, the Museum of 

 Practical Geology, under the direction of Sir Henry De la Beche, the Museum of Bristol, 

 and the rich Cabinet of our esteemed friend J. S. Bowerbank, Esq. We much regret not 

 having been able to obtain the same liberal aid from the Museum of the University of
