NORTH-CAROLINA GEOLOGICAL SURVEY. 



ornamented with varices and spiral subequal striae. Mi- 

 ocene of the Cape Fear 

 river. 



FASCIOLAKIA ACUTA. N. 



s. (Fig. 117.) 

 Shell elongated, a- 

 ctite, whirls about sev- 

 en, ornamented by 

 spiral subequal ribs, 

 with obsolete ones be- 

 tween them, six upper 

 whirls have also equal 

 varices ; longitudinal 

 striae very fine, aper- 

 ture shorter than the 

 spire. Miocene of the 

 Gape Fear river. 



CANCELLARIA CAROLINENSIS. N. S. (Fig. 118.) 



Shell thick, angulated, whirls few, oblique, carinated and 

 ornamented by two'subspinous spiral bands, body whirl trans- 

 versely, rugose towards the aperture, 

 rugae subcrenulated, aperture trian- 

 gular, and acute in front, umbillicus 

 large, open, and funnel shaped. 



I should have hesitated to have 

 placed this interesting fossil in the 

 genus cancellaria were it not that a 

 closely allied species, the C. acutan- 

 gulata, Faujas, is thus referred by 

 high authority. The C. acutangulata 

 is one of the characteristic fossils of 

 the miocene beds of Dax, south of France. Its surface is 

 is ornamented like a cancellaria, but the aperture in both the 

 Dax and North-Carolina specimens is triangular, but both 

 have rather obsolete folds upon the pillar lip ; they are rather 

 more obscure in our specimen than in that from Dax. The
