Paleozoic 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 example, 
but not alterig materially their diameter or relative distanee. 
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 Jone the pyriform second cell, which
