at the base, thickened above, outer lip large, almost semi-circular, 

 with a notch on the upper part. Length, one inch. 

 Locality, Moody's Branch, Jackson, Miss. 



This shell at sight would be taken for a Pleurotowa. It so nearly 

 resembles Conus alatus Edwards from the English Eocene that it 

 may be found on direct comparison to be the same species. 



Fasciolaria Jacksonensis, n. sp., PL 2, fig. 12. Shell long- 

 oval, solid ; whorls seven or eight, convex ; surface with numer- 

 ous revolving lines, and about eight ribs on each whorl ; suture 

 deep; apex sharp; longitudinal ribs on spire rounded and promi- 

 nent, more faint on the body whorl, which is covered with raised 

 lines, alternating with fainter ones ; beak short, recurved ; canal 

 contracted ; aperture oval ; outer lip sharp, with revolving lines 

 reaching the edge, plicate within, plications about eight, not reach- 

 ing the edge ; inner lip angulated and toothed where it meets the 

 canal ; also three plications higher up ; a callosity at the upper 

 end.; callus reflected over the body whorl, leaving a slight opening 

 or false umbilicus. Length, one inch ; breadth, one-half inch. 



Locality, Moody's Branch, Jackson, Miss. 



This shell bears a wonderful resemblance to Urosalpinx cinerus 

 Say, and may belong to the Murices ; it differs, however, in the 

 plications on the inner lip ; it is close to Fasciolaria Moorei, Gabb 

 from Texas. 



Turritella bellifera, n. sp. , PL 3, fig. 1 3. Shell turrited, 

 subulate ; whorls over fourteen ; surface with numerous, prominent, 

 revolving striae, inequidistant, with a number of very fine lines be- 

 tween ; lines of growth indistinct on the upper whorls, increasing 

 toward the aperture ; on the last whorl, and sometimes the one 

 next above becoming plicate and leaflike; lines wavy, bent to- 

 ward the sutures ; mouth rotund, oval, longest axis with the shell ; 

 shell contracted at the suture ; suture indistinct ; whorls shouldered 

 on the upper part, bounded* by a raised line which is itself di- 

 vided in some specimens. Columella with a smooth callus spread-
