This species makes a near approich to A . niusiclina of Mighels, 

 but is more elongate in form, with the lineations much stronger, 

 and never passes into the variety of niustclina with the depressed 

 spire and obese body whorl. The localitv is also different, which 

 is always worthy of particular remark in examining the shells of 

 this genus.— Newc.
