few of which are larger than the others and remote; whorls subearinated 
near the base and. profoundly excavated beneath toward the suture.” 
The shells which I have identified as this species closely resemble in 
their general form a species from the Eocene sands of Claiborne, Alabama, 
described by Mr. Isaac Lea as 7. carinata; but differ in the surface striz- 
The volutions have but one prominent carina, situated near the base of 
the volution as exposed. It is, in fact, the lower angle of the volution, the 
one beneath being coiled a little below the lower angle of the preceding 
volution. Above the angulation there are several (seven to nine) spiral 
lines, nearly all differing in strength from each other. In the single carina 
and in the irregularity and much smaller number of spiral lines it differs 
from T. equistriata, which it closely resembles in general form, except that 
it possesses as maller number of volutions in shells of the same length, a 
specimen of that species possessing eleven volutions being of about the 
same length as one of this having only eight; and the rate of increase is 
also somewhat greater in this one. 
All the specimens of this species which I have seen present the appear- 
ance of having becn waterworn or triturated in sand before embedding; 
consequently the surface markings are faint. I judge that Mr. Conrad’s 
specimens were the same as he describes them, as having ‘‘minute obsolete 
revolving lines.” 
Localities: Mr. Conrad gives as the locality ‘near Mullica Hill, N. J.” 
The specimens in my hands are from ‘‘Cumberland County, N.J., and came 
to me named 7. Cumberlandia, from which they differ greatly. Collection

“Whorls convex, hardly flattened in the middle, with about twelve 
revolving elevated strize, the middle ones alternately somewhat smaller; 
transverse wrinkles distinct.” (Say, in Jour. Acad. Nat. Sci.)
