M. -Edwards and Ilaimc refer five species to JEupsammia, all from tertiary 
strata. The genus is very closely allied to Balanophyllia, differing from it by its 
free, often slightly nmbilicated base, and also generally by the septa of the last few 
cycles being irregularly united to each other.

This is a very variable species as regards the shape of its corallum. A very 
young specimen (fig. 3) is regularly obversely conical, with a pointed free base, the 
calyx was moderately excavated and roimdly ovate. Other specimens arc more or 
less cylindrically elongated and at distances irregularly contracted, but all are 
ciuwed, and none of them show any place of basal attachment. The mural theca is 
always thin. The costfc are nearly all equal, composed of fine granules and se- 
parated by much narrower furrows ; they are almost straight. Of the larger speci- 
mens none showed the calyx exposed, and the septa are only traceable in a section 
of the stem. There are five cycles of septa ; those of the first and second cycle are 
simple and somewhat thicker than the others, but, on the whole, all may be said to 
be thin, and they arc laterally finely granulated. Ail the other septa are rather ir- 
regular and somewhat undulating. Those of the fourth and fifth order meet the third 
near the columella, but generally at different distances from it. The subsequent 
septa are sub-equal, and mostly unite with those of the fourth and fifth cycles, as 
well as with themselves, about half way between the columella and the peripherical 
edge. The width of the columella very nearly equals one-fourth of that of the 
entire corallum ; it is very thinly spongiosc.
