8 Mr. F. M‘Coy on some new genera and species of 
Cyathophyllum pseudo-vermiculare (M‘Coy). 
Sp. Char. Elongate, cylindrical, flexuous ; surface very irregular, 
annulated or transversely nodular, coarsely striated longitudi- 
nally (about six striz in one-fourth of an inch) ; branches ave- 
raging from half to three-fourths of an inch in diameter ; small 
cylindrical branches project at distant irregular intervals from 
the sides: internal structure, central area rather more than 
half the diameter of the tube, defined, composed of flat, slightly 
undulated transverse septa, bearing at their circumference a 
series of from twenty-four to twenty-seven very short, rather 
distant radiating lamelle, not reaching half-way to the centre ; 
interval between this inner area and the walls filled with loose 
cellular structure, formed of small vesicular curved plates, 
highly inclined upwards and outwards. 
This interesting coral perfectly resembles the Cyathophyllum — 
vermiculare of Goldfuss in external characters, but by cuttmg and 
grinding down some specimens of the true Eifel coral of that 
species, I have ascertained beyond doubt (what was before 
suspected by Mr. Lonsdale) that it is not a true Cyathophyllum, 
but belongs to that group which I have named Strephodes, having 
the radiating lamelle extending from the walls to the centre, and 
there twisted together without transverse diaphragms ; it also has 
the curious character of the radiating lamelle having an elliptical 
section, being thicker in the middle than at either end, a pecu- 
hiarity which I have also noticed in a British (Devonian) speci- 
men. of the same species, though not alluded to by Mr. Lonsdale 
in his note on this species in the memoir of Prof. Sedgwick and 
Sir R. Murchison on the Devonian System. The present moun- 
tain limestone coral I have shown above to possess the true Cya- 
thophyllum structure, and it is not therefore likely, after what I 
have stated with regard to the Devonian species, to be in future 
confounded with it. Externally it also bears a strong resemblance 
to the mountain limestone fossil which I have called Lonsdaleia 
duplicata (Mart. sp.), but that coral I have ascertained to possess 
the very different internal structure of Lithostrotion of Lonsdale 
(Strombodes of Schweigger), and it is consequently with a little 
eare incapable of being confounded with the present fossil. 
Not uncommon in the lower carboniferous limestone of Ken- 
dal ; a variety also occurs in the lower carboniferous limestone of 
Kiltullagh, Roscommon, Ireland.

Diphyphyllum lateseptatum (M‘Coy). 
Sp. Char. Stems upwards of 8 inches long, cylindrical, about 
3 lines in diameter; nearly smooth, very faintly striated lon-
