Pal. Univ. 78, M2, 1905. 
Description -—Compressed, whorls half-included, recti- 
and connati-costate; peripheral sulcus sharply defined, 
distinct. 
Distinction :—From 5S. deleta, the umbilicus is larger 
and has more turns. From S. g/evenszs, the straighter 
ribs are not so bold, nor so distant; the whorls are more 
compressed ; the sulcus is more much definite. 
Locality :—Lias, Cheltenham, presumably  oxynoéz. 
hemera.

ie ee 
Description :—Compressed; whorls about half-included ; 
flexi- and connati-costate to subcostate. 
Remarks :—Ribs decline rapidly, becoming very ap- 
proximate and like coarse striz. 
Distinction :—A larger umbilicus and a different style 
of ribbing separate it from S. dedeza.
