.1. multilineata Newc. P. Zool. Soc. London, 1853, p. [38; pi. xxii, fig. 23. 



vShell dextral or sinistral, solid, elongately conical, whorls 6, 

 rounded, margined above ; lip expanded below and slightly sub- 

 reflected, above acute and thickened within ; columella short, stout, 

 slightly twisted, with a callus spread over and nearly closing the 

 umbilicus ; aperture oblong-ovate ; colour of columella, lip and 

 suture white, sometimes tinged with yellow ; shell white, with or

This species makes a near approach to A. mustelina of Mighels, 

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

 and never passes into the variety of mustelina 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.
