A. CRUCIATA Linne. PI. 73, fig. 95. 



Shell oval, moderately solid, varying in elevation from subde- 

 pressed to subconical, usually found smooth, but rayed in fresh and 

 perfect individuals with very fine raised striae. Coloring rather 

 variable, yet almost always exhibiting a more or less cruciform 

 arrangement ; when most characteristic, displaying four broad white 

 rays upon a white spreckled ground of blackish-brown that are 

 usually bisected, as they spread, by a short dark streak which at times 

 becomes so broad as to produce the appearance of there being eight 

 narrow white rays, or of a cross with white edges and a brown 

 center ; occasionally, too, there are narrower interstitial rays besides. 

 Apex blunt, yet prominent, always white both within and without, 

 placed at rather more than one-third the space from the narrower 

 end. Interior with a faint central brown spatula-shaped stain, 

 intersected by the external rays, which appear more or less visibly 

 through the very thin white glaze that lines the rest of the cavity. 

 Length three-fourths of an inch ; breadth half an inch. Worn in- 

 dividuals exhibit a brown cross upon a white ground. (Hanley.)
