 Favauue. 

 Shell from two and a half to four inches long, and the diame- 

 ter at the broad end is four or five lines ; it is strongly marked 

 longitudinally with from eight to twelve ribs and a few in- 

 termediate striae ; the colour is green becoming paler towards 

 the summit and is sometimes stained transversely with darker 

 bands. Gmelin for a Variety has cited Argenville, t. 3. f. I, 

 w hich is very like a fragment of this species with the upper 

 end accidentally broken off. Gualter, t. 10. f. G, from 

 nhich D. arcuatum has been constituted, differs from the 

 common- appearances of D, elephantinum only in being 

 rather more curved and less truncated at the summit. 



APRiNUM. 3. Shell slightly curved, with ten longi- 

 tudinal ribs, and the interstices smooth.

 being white and strongly ribbed without any intermediate 

 strise.

 eight longitudinal ribs, and the interstices 

 striated.
