 The form and sculpture is much like that of M. hebes, Reeve, 

 but the coloring is more like M. crenifera. It is more cylindri- 

 cal and the bars are less prominent than M. cophina, besides the 

 difference in coloration.

This beautiful little shell is easily identified by its dark ma- 

 hogany color and its delicate yellow lineations, like those on some 

 species of Neritina. M. semen, Reeve, which is not so slender, 

 and has fewer and broader lines, is the only species approach- 

 ing it.

A small, very decidedly marked species, most remarkable for 

 the deeply incised, somewhat punctate, dark revolving lines on 

 an ash-colored ground, its wave-like folds and its short rhom- 

 boidal form.
