Long. 35, diam. 18| mil. 



Remarkably close to Mel. hugeli, from which it can be dis- 

 tinguished by its less solid substance, its much more convexly 

 rounded whorls, the last not being [more or less] subangulate 

 as in its ally ; of a plain, uniform, dark coloration ; of similar 

 minute striation, but wanting the spiral sulcations at base of 

 last whorl ; characters of the columellar margin and aperture 

 generally much as in typical M. liugeli. Strongly .decollate, 

 three whorls only remaining.
