LICHENOPORA GRIGNONENSIS, var. MULTILAMELLOSA, new variety. 
Plate 133, figs. 14-17. 
We have discovered some multilamellar zoaria which offer the aspect of true 
Ceriopora because they are altered by fossil izat ion. The fascicles are hardly 
visible, and exact determination is impossible. Nevertheless the cancelli are much 
smaller than on the similar masses of Lichenopora boletiformis Reuss, 1869. The 
superposed lamellae are not always intimately joined; in dissecting- away a frag- 
ment of the upper lamella of a specimen from Rich Hill, Georgia, we have verified 
on the well-preserved lower lamella the presence of the fascicles and the visors 
characteristic of Lichenopora grignonensis. This latter species never having been 
found in all the localities mentioned, we believe it necessary to establish a variety, 
but this is very probably only a simple variation analogous to that already men- 
tioned in other composite Lichenopora. The ovieell observed was concave at the 
center and convex between the fascicles. 
Occurrence. — Middle Jacksonian: One-half mile south of Georgia Kaolin 
Company’s mine, Twiggs County Georgia (rare) ; Baldock, Barnwell County, South 
Carolina (rare) ; Rich Hill, 5| miles southeast of Knoxville, Crawford County, 
Georgia (common) ; 17 miles northeast of Hawkinsville, Georgia.
