THE NAUTILUS. 9 



limestone stratum was dug into it failed as a water tank. Associated 

 with the species is Terebratula wilmingtonensis L. & S., Ostrea vomer 

 Morton and several other species which occur in the white limestone 

 or Jackson horizons. The area surrounding the well is typical Nana- 

 falia lignitic deposits. So far no other outcrop of this limestone has 

 been observed in the vicinity, but careful search is yet to be made. 

 This discovery was called to my attention by Dr. E. A. Smith, 

 State Geologist of Alabama, who sent me a number of specimens. 

 We subsequently visited the well together and went over the locality 

 south of the town, failing to find an outcrop. Dr. Smith thinks his 

 discovery is an " overlap " of the white limestone or Vicksburg, 

 somewhat as in certain Georgia localities. All the different forms 

 of Terebratula wilmingtonensis mentioned and figured by Prof. Dall 

 in Vol. 3 of Wagner Free Inst, of Science, p. 1537, pi. 58, figures 

 14—20, are found here. 



Turbonilla (Strioturbonilla) harrisi n. sp. PI. 1, fig. 8. 



Shell as figured, small, with approximately parallel sides. Whorla 

 eight, the two apical ones smooth ; spire obtuse ; whorls longitudin- 

 ally striated with numerous impressed lines ; base of shell smooth ; 

 aperture ovate, pillar lip bearing one fold. Length 3 mm. 



Locality : Wood's Bluff, Ala. 



Remarks : This species is doubtless the same one mentioned by 

 Prof. G. D. Harris in Bulletins of American Paleontology. No. 11, 

 p. 96, pi. 12, fig. 10, 1899, as Turbonilla sp.(?), but he evidently had 

 an immature shell. Named in honor of Prof. Harris. 

 Turbonilla (Cingulina) anita n. sp. PI. 1, fig. 12. 



Shell medium, spire obtuse, whorls nine, the two apical ones 

 Bmooth, balance with about six spiral impressed lines ; lines of growth 

 very fine and rather close set, aperture ovate. Pillar lip twisted and 

 slightly prolonged at base. Length 6 mm, breadth of body whorl 

 2£ mm. 



Locality : Wood's Bluff, Ala., and same horizon 6 miles east of 

 Thomasville, Ala. 

 Cerithiopsis regularoides n. sp. PI. 1, fig. 7. 



Shell small, fragment from which this description is made with 

 seven whorls ; these have two raised spirals, which form nodules at 

 the intersection with the longitudinal lines. The spirals are placed 

 one above and the other below the centre of each whorl ; longitu- 

 dinals coarse and prominent ; a smooth raised spiral encircles each
