 which the Cypraeae always are, because the mantle of 

 their inhabitant deposits testaceous matter over the whole 

 shell, and because they never have an epidermiSr 



In order to show the various shapes of the different 

 divisions of Cones, we were obliged to give th-em in 

 two plates, the species we have represented are,j 



Fig. 1. Conns antediluvianus, a fossil species from Piacenza, whoso spire- is 

 coronated and more acute than any other species with whick we are acquainted 



2. Conus grandis with its epidermis. 



3. nobilis. 



4. australis.* 



5. an hitherto undescribed species, it is very elegantly shaped and 



beautifully marked ; it is now in the cabinet of the Rev. Dr. Goodall. We hare 

 named it C. ekiplicalv^ , the following are its characters : C. gracilis, subventri-^ 

 cosus, spira breviuscula acuta; anfractu ultimo supern^ rotundatOr lineis, trans-^ 

 versis duplicatis impresso : testa alba, maculis, strigisque fulVis ornata. 



6. Conus Terebra. 



7. Nussatella. 



8. — — — Dormitor, a fossil from Barton, approaching very nearly to a 

 Pleurotoma. 



9. Conus buUatus, two views. 



* In the plate this is called C. gracilis j hut upon exauoMiaftioB we find tiiat it 

 accords with C. australis, Lam.
