ANCILLARIA SUBGLOBOSA. Table 10, fig. 3. 
Subglobose or suboval; spire convex, with the tip suddenly 
exserted and subulate; apex acute; suture obsolete; columella 
profoundly callous, and projecting in the middle. 
Locality. Claiborne, Alab. Middle Tertiary. 
This singular species is perhaps the most ventricose of the 
genus, but has all the characters of Ancillaria. As several in- 
dividuals were sent among other shells collected at random, 
they are probably abundant. 
ANCILLARIA SCAMBA. Tab. 10, fig. 4. 
Subulate, turreted; spire elevated; suture obsolete; columel- 
la concave and callous; aperture about half the length of the 
shell and effuse at the base; right lip emarginate at the superior 
termination; callus at the base elevated and defined by two 
angular lines. 
Locality. Claiborne, Alab. Middle Tertiary. 
ANCILLARIA STAMINEA. Tab . 10, fig. 5. 
Cylindrical, with strong longitudinal lines and minute re- 
volving wrinkled striae; a slight elevation crowns the whorls, 
defined by a separating line; spire very short, apex rather ob- 
tuse; suture distinct; inferior portion of the columella with an 
elevated profoundly striated callus, above which are three or 
four lines revolving to the base; aperture gradually contracted 
above and effuse at the base. 
Locality. Claiborne, Alab. Middle Tertiary. 
Of the species described by Lamarck, this shell approaches 
nearest to Jl. canalifera. These two species do not correspond 
entirely with the genus Jhncillaria , as the aperture is much 
longer, the shells are striated, and the suture is somewhat chan- 
neled. They might constitute a separate genus by the name 
of OLJYULA, and would connect Ancillaria with Oliva .
