Pal<JEOZoic Corals and Foraminifera. 131 



not been able to see the diaphragms ; they are from half a line 

 to nearly an inch in length according to the age of the exampla, 

 but not altering materially their diameter or relative distance. 

 It most usually occurs incrusting crinoid stems or other foreign 

 bodies, from which the tubes radiate to the surface, and I suspect 

 the whole corallum, from the minuteness of its parts, may have 

 been taken for a Favosites or Alveolites, from which the lens will 

 easily distinguish it by showing the reticulated interstices be- 

 tween the tubes. 



Not uncommon in the carboniferous limestone of Derbyshire.

Fistulipora major (M'Coy). 



Sp. Char. Cell-tubes two-thirds of a line in diameter and about 

 their own diameter apart, their walls thick, of concentric lay- 

 ers, with closely placed funnel-shaped internal diaphragms: 

 interstices minutely vesicular, four to six rows of vesicular 

 cells between each pair of tubes. 



The comparatively great size and distinctness of the parts of 

 this coral enabled me first clearly to ascertain the generic pecu- 

 liarities of the whole group. 



Rare in the carboniferous limestone of Derbyshire.

Foraminifera. 



I believe no examples of this group have been hitherto deter- 

 mined in the British carboniferous rocks, which is the more re- 

 markable from their great abundance in the corresponding de- 

 posits in Russia, and according to M. de Verneuil* in America. I 

 may mention, that since the publication of M. Ehrenberg's paper 

 on the carboniferous Foraminifera in the ' Monats Bericht ' of 

 the Berlin Academy, I have diligently sought for the several 

 carboniferous species he describes in the limestone of a great 

 number of different British localities without success. The fol- 

 lowing is the only species I have met with, and I only know it 

 at present from the one locality. 



Nodosaria fusulinaformis (M^Coy). 



Sp. Char. Shell of two or more inflated, pyriform, easily separa- 

 ble lodges, the first one having a small mucronate point at its 

 posterior end, and contracted to a very slender, short neck at 

 the anterior end, which joins the pyriform second cell, which
