This variety, while belonging to the acutum-elaboratum section, 
has a combination of characters approaching other sections. The 
drawings executed by Dr. McConnell, of Washington, show this 
form so beautifully it is scarcely necessary to describe it. 
Prof. W. H. Dall, in Trans. Wagner Free Inst. Science, Vol. 3, 
part 2, p. 323, Dec. 1892, has divided the Eocene Solariums into 
four sections, and, by letter to me, has lately added a fifth, viz.: 
Section Drnaxis Dall. “ Spire flattened, with the circumference 
of shell forming the periphery ; the umbilicus wide, nearly funicu- 
lar, with thread-like spiral ribbing or none, the umbilical carina 
simple or finely granular, forming the base of the shell.” This new 
section includes S. alabamense Dall, and the following new species.
