BULIMUS.— Plate LXXIII. 



On compaiing the shell under consideration with Mr. 

 Sowerby's figui-e, it will be found to be of a more oblong 

 form, more acuminated at the apex, and veiy peculiarly 

 pitted round the upper sutures, reminding one very 

 much of the indentations in the shells of Fhortis.
