few of which are larger than the others and remote; whorls subcarinated 

 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 T. carinata ; but differ in the surface striae- 

 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. (Bqiiistriata, which it closely resembles in general form, except that 

 it possesses as mailer 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 been 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 T. Giwiberlandia, from which they differ greatly. Collection 

 at Rutgers College, New Jersey.

"Whorls convex, hardly flattened in the middle, with about twelve 

 revolving elevated striae,, the middle ones alternately somewhat smaller; 

 transverse wrinkles distinct." (Say, in Jour. Acad. Nat, Sci.)
