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

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

 bilicus ; aperture oblong-ovate ; colour of columella, lip and suture 

 white, sometimes tinged with yellow ; shell white, with or without 

 numerous transverse lines of a brown or black colour. 



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 locality is also different, which is always 

 worthy of particular remark in examining the shells of this genus.

 sinistrorsa, oblongo- ovata, solida ; anfractibus 6, convexis, ultimo 

 paulum inflate ; superficie minutissime decussata ; coloris fundo 

 albido-flavescente ; vittis transversis nigris vel castaneis diverse 

 striato, ant non ; anfractibus superioribus semper nigre et albide

Shell sinistral, oblong-ovate, solid; whorls 6, convex, the last some- 

 what inflated ; white or fawn-coloured ground, very finely shagreened 

 plain, or variously striped with transverse black or chestnut bands * 

 the upper whorls always tessellated black and white ; aperture white 

 or roseate, ovate, effuse below ; columella short and broadly callous ; 

 lip expanded, thickened within and semireflected ; animal light 

 grey, tentacles black, mantle slate-colour. 



Found at Kalai on Tutui trees, and on the broad leaf of the Ti. 

 Has some resemblance to virgulata, Mighels, but the tessellated 

 top at once distinguishes it.
