Observations. This species differs very much from the 

 last described. It is more elevated, without folds, has a 

 smaller mouth, and is striate only on the lower part of the 

 whorl. A single individual only was obtained, the apex 

 of which is broken. 



No species of Fasciolaria seem to have been observed 

 in a fossil state in Great Britain. M. Deshayes in his 

 Tables gives five species, three of which are from Dax 

 (Miocene). In the United States none have, I believe, 

 been noticed. The Valuta Lamberti of Sowerby, has been 

 obtained by Mr Conrad, at St Mary's, Maryland. Mr C. 

 considers it a Fasciolaria.*

 pressed ; whorls , convex ; canal long, straight ;
