A. multilineata Newcomb. PL 29, fig. 23, reproduction of 

 the original figure. "Shell dextral or sinistral, solid, elon- 

 gately conical ; whorls 6, rounded, margined above ; lip ex- 

 panded below, and slightly subreflected, above acute and 

 thickened within; columella short, stout, slightly twisted, 

 with a callus spread over and nearly closing the umbilicus. 

 Aperture oblong-ovate. Color of columella, lip and suture 

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

 without numerous transverse lines of a brown or black color. 

 Length nineteen-twentieths, width ten-twentieths of an inch. 

 Koolau poco, Oahu. 



"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 

 also is different, which is always worthy of particular remark 

 when examining shells of this genus' : (Newcomb}. 



The locality given by Dr. Newcomb is certainly erroneous. 

 No shell of this section, except A. lor at a, is known to occur on 

 the Koolau slope. Newcomb 's shell is well known to be from 

 the Waianae mountains, and probably the type came from 

 Mokuleia district, where it occurs in m,ustelina colonies.
