b. with the tooth obscure or obliterated. 



Shell two lines long, dark horn-colour, glossy and 

 semitransparent : spire composed of six rounded 

 volutions finely striate longitudinally : aperture 

 roundish-oval, with a broad, flat glossy white 

 margin, and a single tooth which is parallel with 

 the margin and close to the outer lip, appearing 

 like a curved continuation of the margin itself: 

 pillar with a large deep perforation behind it. 



This does not appear to be the Turbo Muscorum of 

 Linne, who describes it as having no tooth in the 

 aperture, " apertura edentula " : and no where 

 mentions the remarkable broad white margin. 



Under stones, and in old walls. 



79. PUPA marginata. With a single minute interior 

 central tooth, and a strong white external rib behind
