the remaining whorls also with two smooth bands ; mouth narrow,

This species differs from the Actseon (Tornatella) lineatus of 

 Lea (A. idoneusf Conrad) in having two smooth bands on the 

 upper portion of the body-whorl instead of one. Mr. Lea men- 

 tions having in his cabinet a species from the Paris basin also 

 with two bands, but I fail to discover the same described in the 

 work of M. Deshayes. 



PISAN1A, Bivon. 

 Pisania bucciniformis, nob. PI. xiii., fig. 7. 



A fragment only of this, the first described species of true 

 'Pisania existing in the Eocene formations of the United States 

 has come to my notice. The body-whorl is about inch in length, 

 striated on the inferior portion, and with a slightly impressed 

 line beneath the suture ; mouth about f length of body-whorl; canal 

 almost obsolete ; columella arcuate, wrinkled at base; outer lip 

 striated within by about seven elevated ridges. 



Length ? . 



Claiborne, Ala. 



The Piaania Claibornensis of Whitfield (Am. Journ. Conchol., 

 vol. i., p. 259 1 ) appears from the description and figure to be more 

 nearly related to Triton. 



CONUS, L. 



Conus pulcherrimus, nob. PI. xiii., fig. 8. 



Shell conical ; spire elevated ; whorls about seven, slightly con- 

 cave above, granularly crenulated on the angle, and transversely 

 striated ; a prominent simple line below the angle, and one of 

 granulations beneath the suture. Aperture? 



Length about | inch.
