usually a millimetre ( or slightly more ) wide, whereas the branches 
of the American species have a width of .3 to .38 mm. 
Lophophyllum profunda. Edwards and Haime. ^ 
( ) 
In 1851, Edwards and tiaime published in Polyp. Terr. Pal., 
under the name of Cyathaxonia profunda * a description of a coral col- 
lected at Flint Ridge, Ohio, which curiously enough was overlooked 
in preparing the catalogue of Flint Ringe fossils for the second vol- 
ume of this bulletin. 
Curiously enough both Edwards and Haime, and McChesney 
refer their species to Cyathaxonia, after Lophophyllum had been 
already established. To us indeed the two genera seem to be very 
distinct, but there is no doubt that the species here under considera- 
tion is far more closely allied to Lophophyllwn Konincki than to 
Cyathaxonia cornu, the types of the two genera. In deference to the 
opinion of those who have made a special study of these genera we 
leave them separate, and refer our species to Lophophyllum as is the 
American custom at present. We believe however the L. proliferum 
is only one of the many varations of L. profunda, and should give 
place to the latter name. 
^ “ We know this species only by the interior east of its calyx. The cast shows that the 
calyx was subcircular and deep ;as it is more developed on the side of the septal fossette we 
think that the polyp was curved. The eolumnelia is long and its transverse section sub- 
elliptical , 24 principal laraellse quite large, well developed, alternate with an equal num- 
ber of much smaller ones and arrange themselves about the eolumnella in a somewhat 
branched manner. Diameter of the calyx, 18 mm ; its depth. 15. 
This is really a very g-ood eharac.fcerization of Ohio specimens in the form in which 
they are usually found. But after considerable pains we found a few specimens which pre- 
served the fossil itself. These in the last bulletin we identified with Cyathaxonia 
pROLiFERA of McChcsney. On Plate XII we figured the fossil itself, and on Plate II may be 
found an illustration of the cast.
