alternating coarse and very fine concentric lines, and appearing 

 double from a medial impression (the shell apparently of twice 

 the number of volutions that it a(5tually possesses); base similarly 

 ornamented as the upper surface, convex, and strongly margined 

 by the prolongation inferiorly of the outer wall; umbilical mar- 

 gin finely crenulated, the umbilicus broadly open, and exhibiting 

 the concentrically striated internal volutions of the apex; aper- 

 ture rhomboidal.

kS. huppertzi ^n^ls described from Smithville, Bastrop Co., Tex., 

 in the Proc. Ac. Nat. Sci. Phila., 1895, p. 83, pi. 9, fig's. 10, 

 10' a. We postpone a full discussion of this species till our next 

 bulletin, for doubtless more light will be had on the subje(5l from 

 collecftions of Lower Claiborne horizon from Louisiana. Suffice 

 it to say here, as we did in the Academ^^'s Proceedings for 1896, 

 that this form or variety has much finer markings and granula- 

 tions than typical huppertzi has. 



Locality. — Ala.: Woods bluff; now in both Cornell Univ.
