Specific characterization. — Size and general form as indicated 

 by the figure; whorls about 10, each marked by three strong, 

 spiral lines, the two upper not so strong as the lower which 

 forms a distinct carina at the base of each whorl; suture pro- 

 foundly impressed; lines of growth varying in size, passing 

 downward and backward over the upper two spiral lines, then 

 turning downwards, and after crossing the lower carinal line, 

 passing again slightly to the rear; irregularity of the spiral lines 

 causing a slight ribbing with faint nodules on the stronger spiral 

 lines; on the base of the body whorl there are three additional 

 strong spiral raised lines.

 ledges in the R. R. cut, 2 mi. N. E. of Clayton, Bar- 

 bour Co.

Mesalia?, PI. 12, fig. 3. 



This peculiar little specimen was found at Matthews' Landing, 

 Ala. It is certainly too imperfect for full characterization. 



Impressions of a very similar or identical species occur in the 

 lowest Midway layer (Turritella rock), 2 miles east of Ripley, 

 Miss. , and at the same horizon on Chattahoochee river, Ga.

DalV s original descriptio7i . — "Shell with two and a half whorls 

 besides the nucleus; umbilicus shaped like that of Patulaxis with 

 no rib but, as well as the rest of the surface, finely regularly 

 spirally threaded, the threads delicately reticulated by arcuate 

 lines of growth; form depressed, the umbilical carina simple, the 

 upper surface of the whorls somewhat rounded, but bordered by 

 a double, elevated thread, while the periphery (including the 

 lateral aspect of this thread) has a vertical surface, like the tire 

 of a wheel, which offers three strong, elevated, rounded threads 

 with two fine intercalary elevated lines. Alt. of shell 2.0; max. 

 diam.,5.3 mm."
